230CC iron Eagle heads,383
Wanted to ask and get a little more info on this combination using these heads. Putting together a SBC 383. 4340 3.750 crank, 4340 I beam 6.0 rods and forged flat top pistons. I will be using a flat tappet cam, 2 barrel Holley 4412 Carburetor, not totally stock of course. Turn no more than 7000 rpm's. Looking at a bowtie 23* Intake for it. The heads have 2.08 intake valve and 1.60 exh valves. Are these heads a little much ? How can they be used, if at all on this motor or do i need to wait to build a 406.
