Magnum Exhaust Port Dilema
Porting a set of R/t cylinder heads and they are going to be used with LA style headers. No big deal and this has been done before. Gasket matched the intake and no problems there. Went to gasket match the exhaust and Holy Cow Batman!! The LA gasket on a magnum head is huge. I would shave off alot of metal (See pics) but not sure if thats a good idea. I pulled up the "How to Build Big Inch Small Block" book that I have and noticed they recommend 1 7/8" headers for a magnum head. Maybe this is why?
So should I just leave the exhaust ports alone on these heads or have others ported them out to match or come close to the size of the LA exhaust gaskets?
