Some info for your situation; my results;;;;
550 cu in, 15/1 compression, methanol injection using a Terminater tb. 440-1 heads with 2.30 int, 1.78 ex.
Fully ported by RJ in Iowa, flow numbers were hi from one source(399 at . 800) less stellar from another(370?) Cam- Jones inverse flank roller , standard size core. .868 gross lift intake, .816 ex, lash ,. 019 int, .020 ex. Duration is 284/296/114 . Intake is a 3X. 2 1/4 dyno headers.
Best pull was 926 hp at 7200 rpm. Power still climbing , but not much (1 or 1.5 hp per 200 rpm?)
By my tests, looks like these heads like lift. But then, only three cams have ever been tried. Each one bigger, but other mods to the shortblock.


8..603 156 mph best, 2905 lbs 549, indy 572-13, alky
