Hello

Our exhaust guy is currently doing some claculations for our exhausts. I was wondering if someone could help us with a few more dimensions. We are after -

1) Aproximate distance between the back of the exhaust valve and the port on the head.
2) The diameter of the 'hole' for the exhaust gas to pass through
3) The diameter of the recess that the exhausts sit in.

Any help would be much appreciated

Cheers

Dave

Off my head
- exhaust port to valve stem =3.4 in
- exhaust D=1.51
I am not sure of the recess.

I will update these later if they are way
