Message Well since the heads are the only parts I have not upgraded or rebuilt...there is my winter project. Took heads off another engine I have to get started, presently Z running...OK, needs more, heads are limiting me.

I am by no means a machinist...but understand porting and objectives....so...I thought I would do little improvements from plenum/lower plenum/heads/MS manifolds.

For those who have done this...is it necessary to have the heads thoroughly cleaned before any porting? I would think I could smooth & little grinding before they are cleaned?

Thanks for any input/opinions.
