Additionally the 930 heads take some profiling which is not a big deal and you have to open up the 930 gasket on the base of the head/spacer because the 3.2 gasket doesn't match worth a snot and gives only a few mm sealing on the outer edge. You can also tig a little edge on the port and use the 3.2 gasket if you wish
Hi Stephen,
Interesting what you have said here. I have 930 Heads, and hogged out intake ports to match my 3.2 manifold. I also unshrouded the injector ports a little on the heads. I cut out the intake gaskets to fit. The first go around, I had intake leaks. I pulled the intake off and gooped up the gaskets with RTV. I think they are sealed now. Have you had this issue, an are there any sealing tricks. The sealing surface left after I got loose with the grinder is just like 3 mm or so.
