Iam basically learning P&P work so forgive me on this.

I am working on a 2.2 exhaust manifold, and my question is on cylinders 3&4 there are humps for bolt holes can these be removed or would that cause the wall to be too thin? or should they just be smoothed out as much as possible?

Try to leave it as thick as you can, you should be ok leaving 1/8-1/4" of wall left so it will seal.

You can take a lot more out of #3 if you port a "twist" into the runner as it goes to the collector. Study the bolt boss and you will see what I mean. I ruined one manifold in the process of learning this...

There is a current post at TD that has a link with a picture of what I mean on #3.

Adam actually I wont be needing it now. Once we got to working on it I noticed that it had already been ported. so now I gotta drill for the EGT and port work on the head and it'll be back togeather.
