I am going with a b20 turbo and im completely rebuilding the engine... PYR seems to have pretty good pricing, they will do the porting, springs, retainers, valves, port match IM, multi angle valve job all for $1450.00... Now Portflow itll run you $900.00 plus $150.00 to port match IM, and then you still have the valvetrain to add in which im pretty sure would push above the $1450 mark.

But its not always about the money, i want this done right and would be willing to pay extra to know it will get done right so that is why im curious to know which one you guys would prefer.

 

Portflow

 

Can't go wrong with portflow, lots of people have been happy with them.

Just to cover the entire gamit you may also wana look into Endyn.

I just finished a full race port and chamber rework including port matching on my b16a head. The port matching can be done in the dark. You trace your gasket onto the head and make sure the gasket is big enough for the intake ports. I had the hondata lookalike and it was slightly smaller, after a few touches with the carbide bit it was fixed. Then I traced the same gasket (only now EXACTLY the same size as the head ports) onto the intake manifold (edlebrock) and ground enough off to come very close to matched leaving the intake mani only slightly smaller to aid in the prevention of reversion.

I also did the same thing on the exhaust side and knowing the type of manifold (full race) i am using i was also able to shape the ports a little differently due to the fact that the air is no longer going 90deg down but instead 90 deg up.

The head has been spotfaced to 84.5mm and so now the valves are completely deshrouded - it should perform awesome.

If you're the adventurous type you may wana try it out yourself, if not then in my opinion portflow or endyn is the way to go.

BTW: I have about 9 hours in on what I would call the full race port (significant porting). 2 years ago I did a "clean-up" job with no port matching just smoothing and that took me about 6 hours. The difference is last time I used a dremel and couldn't touch the valves because I had to use them. This time I had a die grinder, extra long bits, valves that have been turned down, and a will to win lol.

Good luck man - let us know how it turns out.
sorry if i went off topic a bit, im pumped to get my new setup together.

edit: reread your post
find a friend who has a valve spring compressor. HAve the valve job done, buy the valve train you want, do the port matching yourself and it should run you sub $1000 for sure. Its nice to get a head that's done for you though im just a cheap bastid and like to take credit for everything lol.

 

I wouldn't trust PYR. They used to be a long time customer of mine. Then they decide to cut off all contact with us and leave a ~$500 unpaid balance. After many phone calls and emails we stopped pursuing. Peter Yem lied to me at least five times in regards to "sending the check today."

I definitely would not trust Peter Yem at PYR with my $1450 cash and a $500 head.

 

I'd go with PortFlow simply because of the awesome track record of happy customer.

Highly recommend.

 

Would any of you recommend a 1mm overbore on the valves? Would it really be worth doing?

Would you overbore on both intake and exhaust or just on one side?

 

because he didn't give ya 500 bucks doesn't mean he doesn't do good work....I have gotten headwork from Peter yem himself....I go down to his shop every now and then, he doesn't excellent work. I was even surprised to see that one of the guys from portflow went to Peters shop to get headwork and tuning job done... Peter knows what he's doing...thats alot more than I can say for most people...dyno graphs don't lie...

 

PYR does do good work if peter or his brother soap does it ,but if his wanta-be wrench-monkeys do it ,you will have problems.plus sometimes it all ways seem to take to damn long .but he has built some bad *** all motor cars ..my freind got some portwork done and it was top-notch work, but that was when it was just him and his brother ,.. good luck and hope this helps.

 

I will also vouch for Endyn. Larry's heads are a work of art.

 

im basically rebuilt with Endyn and Portflow...quality...

endyn pistons, valves, oil pump, oil catch...

portflow inner springs and retainers...

haha.. another one bites the dust. "I wouldn't trust PYR..." "check in the mail" ...sounds so familiar. damn, i didn't know he was still jackin' people.

peter CAN do AWESOME headwork. i had a fast car!! ****, he had my props when i pulled low 13's all-motor back in '99 from a head ported by him but i say **** him... bad business ethics. he'll get what's coming to him. why do you think he left cali?? 'cuz he fucked over so many people over here that they all want to kill him. glad he's over in texas or wherever he's at now 'cuz i prolly would have killed him too. is that a threat? oh well. come back to cali peter, and we'll see what happens. KARMA BABY!!

anyway, enough of the rant... go with something other than pyr. atleast you know the other companies won't run with your hard earned money.

whew... this thread pisses me off cuz it took me years to forget 'bout PYR. now it got me thinkin bout that fool... first my roadrage now this... i better get a beer.

Portflow

We work with Tom all the time. Can't beat the turnaround time nor the quality.

If you are looking for someone that is consistent = Tom @ Portflow

 

The head was good work, but on general work that peter doesn't do is subpar. Nothing like going to pick your car up and it runs like ****
