If the heads haven't had the guide heights modified then the valve lift limits are about .535" maximum.

just talked with scotty , got all the info i needed and the right parts ordered

John I would recommend you get rid of the stock valves if you going to be turning it very high in rpms.Randy has some nice stainless valves at a good price just remember the old factory valve are 42 years old.

maybe 5500 is high as i plan to go, the motor has 22,000 original miles on it, i dont like to be cheap , but this is a major budget deal, whats the biggest cam a stock spring can hold

The stock valve spring will accept more lift than the head itself will allow. The stock spring pressures will be down from a good replacement.

a set of decent springs and retainers is under $150........

was looking at another cam..it has .503-.503 lift, but a tad more dur then the voodoo..2000--5500 rpm(summit racing cam)..that is under the max lift the head will handle , just concerned about the spring pressure, trying to save some $$ and not have to get springs..retainers..etc..even though they are only 110.00

Stop being so damn cheap......... put the right stuff in it...... its not worth the argivation of doing it twice over $110 worth the parts.

Just a few months ago I lightly tossed some OEM 429 CJ valves into the bead blaster for a quick clean-up. When they landed in the bead blaster, one of them promptly broke into two pieces right where they are welded together. Yes, they are 40+ year old two-piece valves and so trying to save money in this area brings a tremendous risk of costing you your entire investment down the road if you dont upgrade now.

That cam is a turd not to mension that its a chevy grind with square lift and duration. If you use that your motor will be done at 5k or thats what it did in a 460 that I had years ago. Get yourself a kit with the springs/hardware and the valves. If the motor drops a 42 years old valve (likely) its gong to cost too much.

Do Ya Feel Lucky well do you that is what the late Mr Chuck Stevens ask me but here read these
