Exhaust Port to Header Flange
I was fitting my header gaskets tonight and realized my Edelbrock Aluminum Heads (which have been ported) have exhaust ports that are approximatly 1 1/2" h x 1 3/8 wide. My headers measured inside the flange is 1 1/4 " h x 1" wide. What to do - I don't think I can grind enough off the header to get it the same size. This seems to be a rather large restriction, almost 50% and wondered how much power I might lose. Any suggestions appreciated. Most of the area inside is weld bead and I'm afraid if I grind it out the header may fail.
