Totally Dissapointed!!!!!

Did you look into the valve cover baffles or not?
If they aren't there, the oil usage issue stops right there, IMO.

Also, the 318/360 Performer is a good design of intake, but in order to get the large port you MUST grind the the opening of the port to get full effect.
It tapers out to 340-360 sized porting @ 3/4" down the runners.

An engine builder guy I know has always said "95% of all 'faulty' engines I've built turn out to be 'installer error' when it all comes down to it".

For the most part, I agree, but I still final-assemble the stuff myself.

Mark.
