Wow this thing needs major help and I honestly don’t know if it’s doable. I will post up flow numbers hopefully later tonight. This thing at .500 lift is sucking well over 50 plus horsepower out of my ported heads. At first glance it doesn’t look bad as far as gasket matching but it appears to taper in badly past the entrance. Matt and I both use the Mr Gasket intake gasket number 7276.

I figured I better order a new Foredom hand piece since I have been porting more lately. I had not having spares. Here are a few pictures of gasket layout and a couple getting opened up.
