I was wondering how far I should get my B18b head milled, for higher compression? What kind of Hp gains could I expect? Decided not to go with valve job, saving money for gsr head.

None, just get some high compression pistons. Milling the head dicks with valve/piston clearance too much. Do it the right way.

<whore>On that topic I have a set of LS rods with B16 pistons (yeilds around 11.4:1with LS head) on them that I will let go pretty cheap, PM me if you are interested.</whore>
