Headwork On Xu10J2

[Pugrich 4 2 Cars]

Hey, a friend is building a 306 XSi engine and is searching for a little more power :-)

 

He allready bought a Schrick 268° cam with about 11,5 mm camlift! Management will stay stock. So the question is how much to skim the head to get the optimal CR.

 

Thx, Rich
