your ported stockers should be fine..what valves do you have in stockers? the 64cc is octane freindly

MKS

they are just ported with stock valves so they are basicllay stock and need to be upgraded

save money if you upgrade your port job, then get new stainless valves rather than buying a whole new set of heads. if money isnt issue then get AFR Stage 2 64cc

MKS

it will cost me to get the valves and double springs and thats why im getting the patriots with the gold springs and bigger valves but not sure which cc and what pushrod size need

Ksett

Go with the 59 cc's and check the pushrod length and you will be set.

It depends on what your plans are for the car personally i would go with the 64's.

I had 59cc ran great no problems at all, used normal 93 octane. 59cc = 11:1 CR 64cc = 10.6:1. I'd personally go 62cc or 59cc for N/A application.

11.35 SCR is the compression you'll have with 59 cc

But looking at your sig, $$$ shouldn't be a problem for you (unless you're a car dealer), so I suggest to get AFR milled to specs with the size gasket he was running.
PM him, he'll set you up for the best CheaTR combo.

My AFRs are milled to 63cc. Close to the line, but nothing to have to worry about

You need to find out the intake closing point at .006" on your cam and then figure your dynamic compression. Keep it around 8.5/1 and your good.
