dwayne, what size bench do you have? just curious.. i have a superflow 600, and im looking to get a 1020 soon. i go along with dwayne on the porting small block stuff, ive done some nhra stocker small block stuff and think they are around 190/150 with a 1.88 and 1.60. ive done s/s stuff that flows 260, 240 at .400 lift that goes fast. with those things, as with alot of things, the low lift numbers mean alot.
