Full marks. Measured for your convenience.

Full story here:

Engine building 101 here:

I welded up the port with NiRod and then ported from there. You can also gain some flow on the intake by turning the round port into a D with a little Devcon or JB-Weld.

I'm also working on a stainless header that can have a tab welded in...but that's a bit longish term right now.
