When mix matching different parts, especially with a home made turbo kit, everythng diesn't always line up perfectly.
Here is a used HF manifold that I bought for cheap. I read that the manifold should be port matched to make bigger HP #s.
When I looked at the ports, I saw that someone had already done a little work on them. You can see the top of the ports have been slightly enlarged. So I am going to improve it.
After getting the dirt etc. off the surface, I put the exhaust gasket over the surface. Then put slightly larger bolts in the holes to eliminate any play or movement. The bolts need to be as tight fitting as possible. Then traced around the eage of the gasket openings with a fine sharpie.
Here you can see the line I made with the sharpie. That's as far as I will be removing material.
Use a die grinder and wear eye protection. The material will be removed as small flying iron splinters.
