Which heads to run on 340

If i was building a 70/80's type car, and this is just me personally, for mainly street and a little playin' on the track, i would run a flat top piston similar to this....http://www.summitracing.com/parts/SLP-L2316F30/... and shave the "J"s down to around 65cc's and with a deck clean up and a .028 gasket would be around 10.0 to 1 compression. I'd keep 2.02 int. valves, with a good multi angle valve job and a little bowl clean up. This would allow for a little milder cam, low/mid 500" lift and 245ish duration at .050 to allow for a decent signal to the carbs on a tunnel ram. Along with a high 3/low 4 gear it should make a fun ride on the street and still be pump gas friendly. jmo
