Looking for Advice....
I have been in contact with several Cylinder head porting companies and Lost as to which one I should go with. I am currently leaning twards DPR due to the time and attention they have spent on my design and set up. Alaniz and Portflow work looks Good and they also carry a good reputation, but I am still unsure of what company to go with. Any help is useful.....

 

These guys are all Klownzzzz.

Oddly enough there is only one man on the planet earth who can really port a Honda head.

I can't tell you who he is though.

Scott, who doesn't care what anybody says..."I don't need Headwork!"...

 

a DPR head for a ITA CRX is proven power. i recommend him.

 

Comptech is another possibility. Though I don't have experience with any of them.

My work was all done by a local with flow bench

He used to work for Jack Roush. He also does work on a lot of pro road race stuff. Very knowledgable guy with lots of trick headwork.

I give Alaniz props for seeing their cars on track...

 

ALANIZ We proved it at Infinion... And will do it again this weekend at Buttonwillow.

alaniz did my head. they hooked me up very well. i give them lots of props.

i have heard good things about RLZ too. along with others.

 

Great thread. I had been wondering the same now that I have an entire year to get the car prepped finally to the extent of the rules.

Anybody have the contact info for these folks, other than Portflow?

Thanks.

I second that. I havent had work done by him, but Brad spends 30hours on every stage 2 head. I've seen pictures of his work, and it's second to none. His prices are also kickass.

I know many can attest to the DPR heads in ITA... The guys running DPR heads from Street 'N Track Autosports have set several track records and I've heard DPR come highly recommended from others as well.

I got a bargain on an old Sunbelt worked head (and I mean bargain) but would have gone with DPR if I could have had the funds. I made another 4whp/tq from that old head, which puts me at 121whp/110tq on a stock bottom end with OPM header/exhaust. If and when I shoot for the 130whp range, I'll send one of my spare heads to Dan and hopefully pickup a SMSP header. I called DPR before I had the opportunity to get the used Sunbelt head and talked to Dan's assistant about pricing. Dan personally called me not once, but 3 times to see how my race season was going and ask me about my goals and such. He called even though he knew I couldn't afford his work at the time. to Dan.

 

I can tell you dont let anyone do the head intell you know that they are Honda guys, make sure they know the engine. We missed up once but it wont be like that again. Joe makes the best Honda heads, trust him. And if its for ITA keep it away from Joe.

 

portflow...alaniz...whatever they're basically DPR ver 2.0 and 3.0 lol

Brad is a Very very good head porter. I have gotten my head done by brad. the only problem is that it isnt on my block yet. hahaha
He knows his stuff and like the other guys said he spends about 30hrs on a stage2 head.

 

I had my B16A head ported by Joe Alaniz. After a brief interrogation about what cams and pistons and rpms that I was planning to run, he took the head and did his magic. Then it was ready the day that he promised it would be. It has served me well this year. I would highly recommend going to him.
There are good reasons to go to Alaniz like him having his own flow bench and that he has a great reputation. But I would go to him because he is a huge road racing fan. He and Tsuyoshi from 5Zigen are the only two industry people that have been out at just about every WCHC race this year. At our last event he chose to come out and support us up at Sears Point when his real money making driver (Eric Agular) was drag racing at Pomona. I feel that whenever possible we should support the companies that support our sport.

Good stuff

 

interesting that no-one has mentioned King... Don't they give, err, machine good head? (sorry couldn't resist - please dock points as appropriate)

 

DPR took eight months to do a friends head, and gave him a big run around on it, with a different excuse each time. I'd be wary

That's the reason I wouldnt' use DPR. I'm not a "special" customer and would get to sit at the bottom of the line while they worked on higher priorities.

I mentioned this in another of this guy's threads, but I sent my last head to Alaniz. I was happy overall - despite them throwing away a set of springs that i wanted back.

Any future business will go to Brad @ RLZ.

 

What is considered Good or Average Turn around time?
Did you send it threw a shop or direct?

 

is always good to go with a pro when you are dealing with head work.
bad port work will hurt more than the gain.

Stay away from DPR.

Portflow and Alaniz are all good.

 

Thanks for the advice.... I read your post and it sounds awful.

I was looking at his cams also, and I read the warning on the site

!!! Warning Race Use Only !!!
Due to the aggressive profile of these camshafts, we recomend that they are only tuned by a Professional Engine Tuner that fully understands their limited cam timing adjustment. Failure to comply with these limits may result in Engine Damage or Failure. Please contact us for additional information.

So I contacted him about this warning, His engine builder explained that due to the lobe separation when install at 0 and 0 they can only be separated a max of 5 degrees off of center, before valves collide.

After knowing this and reading your post, I have a few questions as to who is actually at fault.........

Let me get things strait
- The engine was running perfect
- Dan clearenced the pistons and clayed the motor to ensure proper clearence
- Dan set the cam timing
- Your Mechanic Finished the installation
- The timing belt came off due to inproper installation,
- Everything checked OK and the Engine sounded strong
- VTEC Solenoid Worked before and Doesn't Now?
- Mechanic forgot to plug in or mixed up VTEC solenoid plugs!
- Engine never ran in VTEC while Dan was present? For $9000
- Then never ran the Motor until race day to make sure VTEC was working!

I have a couple of thoughts on this..... I am not taking sides, but I am used to watching my ***. I would have paid an extra $300 for Dan to catch a later flight until I saw a Hot Lap. Second It sound Like your mechanic is not very competent. First not setting the tensioner properly, and Second not plugging in, or crossing plugs to the VTEC Solenoid (It wasn't bad.... the motor ran perfect before Dan).
Third if that was my mechanic and he made minor major mistakes like that, there is no way I would let him near the cam timing.... Especially with the sensitive nature of the DPR cams. Say for instance he advanced the intake One degree that could have been enough to send valves colliding. I don't know who to blame but I have blown up motors in the past myself and usually the final finger gets pointed back at my self. If I were you I would start with a new mechanic.

 

Go with RLZ, I have seen his car run, been to his shop a couple times to have a R head looked at, and seen his work. Very helpful and knowledgeble.
