They did not flow the heads he had but Cogswell does have a flow bench. I think it was more of a visual and the fact that he didn’t hit water “good”. Cogswell’s main business is Volvo Penta boat engines but they build a lot of engines. Mitch Cogswell is a LA Mopar guy. He has a Dart and I think a Barracuda.
On the heads I’ve got going right now I just want some blending and clean up. These are for a 408 Six Pack build. My dad didn’t want to do aluminum heads and wants to maintain the factory look for his ‘70 ‘cuda. I am giving him the heads, new H-beams, double roller timing chain, 73 360 block, new ARP main studs, and some other miscellaneous parts. He will be putting my Keisler TKO kit and driveshaft in it and I will be putting a T56 in my ‘cuda eventually. He’s ditching a hot 440 and automatic to go small block and manual.
