I need some help in determining which heads would be best for a 355 qu. in. Chevy engine. I want to use AFR heads but I am having difficulty in chosing between the 180 cc 195. I am planning on using a forged crank and also forged aluminum pistons, compression ratio 9.5 to 1. I will be using a comp cams hydrolic roller XE276HR which has a duration of 224 on the intake and 230 on the exhaust. Intake manifold is a dual plane.
This engine will be used in a 32 Ford Roadster with a Tremec 5 speed transmission and 3.73 rear end gears. The car will be used almost exclusively on the street. I could also use some suggestions on which carburator. I am contemplating using a Holley double pumper. I am not sure which CFM would be best.
Any suggestions would be appreciated. Joe
