So I'm pretty heavily invested in my m20 stroker engine build. I have 85mm Mahle forged pistons M52B28 crank Schrick 272 cam and valve springs and IE heavy duty rockers. I had kinda overlooked the fact my donor engine does not have the original 885 head but instead has the aftermarket AMC head. There is plenty on the interwebs bagging the head due to the port design and finishing. The ports are pretty rough from the factory casting & machining. On the other hand companies selling the AMC head state they are a solid base for race applications.
Has anyone had experience with these heads good or bad? Should I clean up the ports and carry on or find a genuine 885 head for my build?
I should say I'm building the engine as a solid engine for my daily driver that might see the odd open day at the track once a year.
