whats the thinking behind the exhaust port exit? I've personally never seen anything like that

Looks good so far

The idea with the exhaust port is to smooth it out and open the window without messing with the radius and not to overhshape the roof

the exh port on the e7 flows best in the top half corners and walls by making this area larger/smoothing it increases flow mainly at higher lift overdoing this can hurt low lift velocity in the same area

i dont port match exhaust if you see the circles scribed on the exhaust thats my port size in the header the header I.D. is matched to the gasket other than the bolt area

when i port match the intake i only open it up to the smallest pinch i have in the intake runner (pushrod bumps) not the entry size
