Title: Single VS twin port exhaust location
Post by: spoolin70 on October 25, 2019, 21:16:45 pm
An easy answer for someone in the know I'm sure -

Are the exhaust ports in the same relative position for twin port and single port heads ?

I'm thinking of some parts for a mock-up engine and one of the things I'd use it for is making a turbo exhaust manifold. I can possibly get some scrap single port heads but was wondering about the exhaust position.

Enlighten me oh wise ones  :)

I'm going to say yes. I used the same header on a 1600 single port in my first car as the 1641 twin port in my next one, so if there is any difference, its negligible.

Perfect !!

Thankyou Neil  :)

It didn't occur to me to use exhaust compatability as a reference. Really didn't want to use my 'good' heads for mock-up.

All the best
