Is an Indy SR head enough to feed it. Heads are ported some but I don’t have any flow numbers. 11.-1 compression. .650 lift solid roller cam. Victor intake and a Pro Systems 1000 4150 style carb. This will likely end up in my 74 duster race car. I do have a set of Procomp Victor knockoffs that are CNC ported. And a set of Mopar Stage 6s that are ported as well. No numbers on them either but on a mild 470 stroker they made 655 hp and 620 tq. If I were to use the stage 6s I would need intake spacers or find the rare Mopar intake for them. Thanks. Kim
