I started a thread a while ago about my allpro heads. Now I have a little more $$$ to buy the valves and springs to get this thing rolling. Bob from allpro gave me a idea of price and needs info for the valves. He said he needs to know spring dia., coil bind pressure, and installed spring height and spring poundage. I'm a newb when it comes to valvetrain so, help me out guys. Is there a standard valve length?

Heads already have seats installed and cut along with guides. Valve sizes are 2.05 and 1.60". Stock rockers will be used and I don't have push rods yet. Cam is a 236/236 .587/.587


thanks in advance guys !

I would think a set of patriot duals would work, just buy the kit, they come with spring cups and everything, you can machine the heads if need be to acheive proper spring height. Not sure on the valves, wish I knew, I've never run allpros. =\

Wouldnt it make more sense to let the head builder/supplier, spec and supply everything and assemble them ?

Hmm, etp, I'll take a look. I was also thinking dual 921 or patriot gold. Cam is under .600" lift. Dual spring for sure.

I didn't have the cash to buy everything assembled so, now I'm buying the valves and springs, seals, locks, etc and going to assemble them myself. Bob that works @ allpro asked me these questions when I went to him to order the valves. The car is a pump gas DD so, I want to make sure I pick the right components and do it right the first time.
I also have a choice between ti and hollow stainless for the intake valves. Ti is twice as expensive as ss.

The cuts for the spring seats are HUGE, I'm pretty sure machining is not needed. I hope I won't have to machine for spring pocket depth. If that's the case, I'll send them to w2w for that plus some porting on the exhaust side. Really though I want to see how these will do unported and save my money for the missing parts to complete my car.
