Hello H-T,

I was in the market looking for Race cam setup for my race car (Ferrea Roller / Web Pro) for some time and I found a good deal on Web Pro cams with rockers, spacers and VTEC block-off plate.
After I receive them, I found out the cam card mentioned those are (stage 1 / Part # 35-442) but the cams I received are 2 lobe cams.
When I checked the stamps on the cams, the numbers are for stage one cam (492 on the intake cam and 737 on the exhaust cam).
I couldn’t believe what I saw so I decide to measure the both cams lift and this is my finding:
Intake cam lift: 0.515 inch.
Exhaust cam lift: 0.495 inch.

Also, I have noticed that retainer to valve seal clearance is 0.025” and cam lobe to cam cup clearance is less that 0.002”.
So, is there any one hade same issue with the cam card or stamps?
And, what are your retainers to valve seal clearance and cam lobes to cam cup clearance?

Thanks in advance.

MrParks

we do not use valve seals with our setup.

Let the HT freak out begin ....lol

sheepey

who did you buy these cams from? That is very odd we stamped the stage 2 grinds on the cams.

sheepey

if you have less then 2 tho of clearance is because the guide needs to be pushed down. Which should be done before the valve job. You cant just drop these in.

harhoosh

I think you miss understood me, the less than 2 tho is between cam lope and camshaft cap (the long two cap) that's why I took the cap to the workshop to mill 20 tho from them.

Regarding the guide, web recommended 0.030 min clearance between retainers and guide but what about retainers to valve seal min clearance?

I bought a member from here, so I don't know from where he bought them.

sheepey

ohh Im sorry, I did misread your post. That is normal depending on the cylinder head.

harhoosh

So, am I good to go with 0.025 clearance between retainers and seal?

Thanks.

sheepey

yes sir.

harhoosh

You made my day sir .

Thanks a lot

I was shocked about this when ordering my cams... But soon found out alot of people are actually running like this

cibao2ner

so no valveseals.....this is on racecars only right...and also doesnt oil get into the combustion chamber and increase chance of detonation?

I guess when you think about how a car acts with bad valve seals it makes sense. There will be leakdown of oil into the cylinder after it sits and get a puff of smoke on first start up but then really nothing while driving. So there is a minimal amount of oil that would actually make its way into the combustion chamber during normal operation. You would likely in a race only application prefer the benefits of ensuring enhanced lubrication to the valves and guides over a very minimal amount of oil being introduced into the combustion chamber.

Just gotta vent your valve cover really well and it's not a problem....

harhoosh

So, most of the web pro cam users running them with no valve seals?

tepid1

I use seals on my car, but the work done to the head allows for them with Web Pro's.

harhoosh

Care to share what have been done to your cylinder head? You can pm me if you don't want to share on line.

Thanks.

It's a RLZ "outlaw" head with bronze seats and bronze guides. Nothing crazy, just prepped for the cams I'm using. I came up with .019 between valve seal and retainer. Plenty of room. Lol

I don't use special Web cams. Just their shelf Pros.

sheepey

Doesn't get much more special then that brotha!

harhoosh

Which mean I have more clearance in my cylinder head .

To sheepy,
Are my finding lift measurements right? Or I suppose to get same as the advertised numbers?

Thanks

Divers

Hell no. We run valve seals. Should be fine with pro cams, they're not that crazy. Sink the guides if you want more clearance.

Divers

I wanna know what kind of lift you're running that you can't run valve seals!? Second, what springs allow that kind of lift and not bind?!

harhoosh

I was thought that I need more than 0.025 clearance but Mr. Sheepy confirmed that I will be fine with what I have so, no need to spend more and have more headach on that peice of crap.

Thanks every one for your inputs .
