ive got a friends x-flow kent engine that he wants the head porting a bit.
the bottom end has just been rebuilt by autosprint 1660cc
any info on porting the head on these beasty's??
obviously the ports need cleaning up and all the casting marks taken out.
whats the gen around the throats / valve seat area and valve stem holes??
the inlet ports right by the manifold are quite chamfered so these need to be smoothed out i guess
anyone have any good advise on this prehistoric head ???
