alright, i bought a '91 GT. i bought it from my cousin who got it from a guy in TN that he knows. the guy said that the car has a 302 block with 351 heads, with a five nintey some-odd lift cam(don't really know for sure), Edelbrock performer rpm intake with Holley 750 carb.

i have a few question about this setup. a friend of mine told me that you can only run up to a 1.90" valve or it would slap the piston tops. i would like to get a set of trick flow heads for a 351 with 2.02" and 1.60" valves. these heads will be on a 302 block bored 30 0ver with a 347 stroker kit in it. would the valves be a problem with that setup? if so what pistons would you recommend to let me keep a 10:1 compression ratio? what about cam size?

thanks for any info that you could help me with guys!
