Thanks Dean,
I plan on using AFR 185cc heads. Their specs say with a 4.060 bore @ .600" lift = 277 cfm int. and 199 exh. I still cant get my head around how when one cyl. theoretically only needs 85 cfm @ 7000 rpm, I will be supplying it with a venturi that can support 320 cfm. I figure it would result in a crappy vacuum signal at transient throttle positions and driveability issues. I guess everybody has good luck with them, and besides it wouldn't be fun to me if I didn't have to tinker with them and they look so cool !
Regards,
Scott
