[effvee]

Hi everyone, I am getting to a point where I can get the second spark plug hole installed. I un-did some of my last porting, due to having seen someone else porting which I felt was much better. These heads are from a 411, they were from the 1.7 engine. I think the exhaust is 39mm X 41 or 40mm. Have a look and make suggestion on any imporvements I can make before the plug addtion and coating and "O" grooves.





This is the flange, the exhuast pipe will be welded to it

I will need to have the seats re-ground.
Hi, am havig my machinst mill me a "O" ring groove into the head and cylinders, man I need to get this engine running.
