I just ordered Mac long tubes, and a o/r prochamber. My question is what kinda header gaskets should I use to minimize leaks? Also What lenght of o2 extensions do I need?
make sure you take a file or dremel and clean up the slag near the header flange, other then that the headers are great for the money. I use a Percy multi layer gasket and they have always worked for me...can be found on ebay for like $15.
Hopefully copper ones work good. Dallas mustang said they were the best. Cant wait to get this stuff ^-^. Got the ceramic headers and the stainless steel prochamber with mac dumps :banana:
use ANY gasket that is a multi-layered steel. IE, stock, percy copper, Felpro, etc. do NOT use those stupid paper gaskets they include, they'll blow out 10 minutes are the first tim you start the car.
