Thread: Anyone have a good way of blocking the exhaust crossover ports on FE390 Heads

Tweet

Hello friends. Just got my Edelbrock Performer intake in for my FE390 and getting ready to install it. I want to block the openings on the heads which are next to the intake ports #7 and #2. I think that these are called the intake crossover ports but I may be wrong. I'm including an image of #7 intake port and the port in question. The other is next to #2 intake port. I was going to use a very thin metal with just a pinch of gasket glue to hold them in place while I install the intake but wondered if any of you good folks had a better solution. I'm not as concerned about blocking the intake as I am about making sure no oil seeps into the port on the head as the exhaust valves #7 and #2 located inside these ports were blowing oil into my headers due to a problem with my previous intake and the fact that I didn't have nothing but intake gasket material covering these before. Any tips about doing this would be greatly appreciated. As always many thanks for taking the tiport2.JPGme to help me. Can't wait to get this car running smoke free.
