Man I gotta raise what I charge to port intakes

I appreciate it, but that didn't really answer my question. Probably my fault though. What I meant was more - Could gasket matching a port opening in the intake and cylinder head be detrimental to making power if the rest of the port on the intake and cylinder head are left untouched (ie. smaller than the gasket section of the port)?

I've got the tools and know-how to do it and have done it multiple times. I'm just curious if it's even worth the effort if ultimately the result is a port cross-sectional area that opens up and necks back down. I guess it would depend on the amount the port needs to be opened up to match the gasket?


If you were only going to open the head port entrance without addressing “the pinch” I honestly think you are doing more bad than good.
