Would love to see that exact set up repeated Dwayne , but with the 270 heads and Trick Flow Intake, and then other intakes.

I do think it helpful Andy did a baseline set of pulls with the 250 heads since he changed from wet to dry dump.

Andy- Did you stay with the 10.5 compression of did you bump it up?
I seem to remember a post about bumping compression a bit- but may be mistaken.

Also wondering what manifold vacuum and CFM flow differences are noted as due to head change.

I have friends here very close to pulling the trigger on the 270 heads , however, as Dwayne mentioned in one of the threads- the 270 heads might not be the value the 240's are.
Thus- All my questions.
