Thanks guys, just wanted some reassurance before spending the dough. The current heads were 906 open chambers on top of gaskets with a compressed thickness spec of around .040 if I remember correctly as I had ordered a replacement gaskets before the head fell

Regarding the intakes I think we will try the Holley street dominator we have on the shelf, I know it's not as good as the rb version or the Performer from, but might as well give it a,shot
