Just after a little confirmation that what I'm going to get done to my 2g head to fit my 1g block (been reading too many US forums) with ARP studs is correct. I'm doing the oil port mod myself, and I'm going to get the head shop to take the bolt holes out to .5 inch. To go total overkill I thought I'd get the hole with the oil feed taken to 13mm just to where the oil galley comes off. I'm not worried about too much oil in the head as I'm using a Kiggly hla, which restricts excess oil rather than just dumping it into the top end.
Does all that sound right to those that have been there and done that?
