just like the title says should i mesage the inside of the header that i ordered from rsm?
there is a couple of rough spots and the flange is really square around the ports. do u think i should make it more flowing?

thanks for the help going to install real soon

i don't think messaging it will work , since headers can't read.

Now if you mean massage, as in clean up the runners a bit from any flash and do a quick port match to the gasket (will only really do you any good if the head is port matched also), then it won't hurt and might squeeze an extra pony out.
