Let er rip boys.

They are Visner Super Chief's that are canted also.

I'm sure it was a rough road to get that tank to do what it's doing but it's dam sure delivering the pain now. Very impressive

i question the definition of 'canted' vs 'rotated'in this post...
this is a technical discussion which will bore most here, so please indulge me-

definition(s)-
rotated- difference of primary valve angles from intake to exhaust.. for instance- stock pontiac post '67 valve angles are both 14*. 'rotated' term refers to change of that # from 1 valve to the other. as example- if intake primary angle is 14*- like stock late pontiac, and exhaust is 10*, then rotation angle is 4*

canted- refers to the lay over angle which is perpendicular to the primary angle-
the action of valve opening into the bore creates separation from the cyl wall... more lift creates more separation. so canted angle of 5*, like cv-1 creates bore separation @.500" lift that makes 4.35" bore appear as 4.45' bore due to valve lift

when evaluating pics of valve layouts, these definitions will help the viewer to define movements.

Perhaps the pictures don't show it well enough, But the lay over angle is far different between the intake and exhaust. BUT no where near as much as Jacks or a BBC. They are goofy weird heads but I'm happy with them so far

i remember you ran 7.90 at norwalk few years ago with your eheads. have you run the quarter yet with your billet top end?
