E31 Exhaust/Intake Ports

https://www.classiczcars.com/gallery/image/10317-e31-exhaustintake-ports/

Porting/Polishing is nasty, tedious work. Intake valve runner port matched for intake manifold for triple Weber DCOE 45's and larger intake valve. Exhaust port was left alone.

Won't this make selling cars a lot more difficult, misrepresentation and all that jazz? @URGELIS could retire a rich man.

I know a few people were following along on this- been a while since I last posted here- but finally all came together!
Mounted up and running strong! Still a few details to work out; but runs good, sounds good, feels good on the initial pulls. Super happy it worked out!

Well I decided to go for it -

Went with 42's and a TWM manifold. Still lots to sort out, but Ill start another thread on it somewhere and link it back here. Rought calculations hopefully put it in between an OER setup and a Mikuni PHH setup $wise.
