Okay did the oven cleaner last week. Took a couple or go rounds to get all the crud on the exaust side, but its "clean...er". No crud, but I am thinking maybe a little porty/polishy? Something to klean up that area between the "pocket" and the manufold. Always willing to entertaine new ideas...........(for $10 or less a plate).
I do know that I drive torque, while listening to my friends prattle on about horsepower.
what about a dremel motor and a honing stone to remove the cast flashing?
I have both a dremel knock off and an electric die grinder. I use the grinder stones only to remove flashing, I was understanding that the ports should remain a little rough for air the air to mix better.
like this you mean one inlet ported out to match the gskt and then polished...I read somewhere that the exhaust port on turbo heads just needs cleaning and NOT making any bigger, to keep the exhaust gas speed up to help spool the turbo.(un-less i'm going mad)
