M42 head's oil galley's not matching up to block

Im rebuilding an E36 M42. The head on my M42 was cracked, so I got a new one with the machine shop. There are a few M42 heads out there; e30, e36, then we have the M44. Anyways, the part numbers match, but the oil galleys from the head to the block dont match up 100%. Its definitely not an e30 head because it doesnt have dual-springs. There seems to be about 30% off-center from the block and head. Is this okay? Is that how it is?

The head seems to fit on 100% ok minus this.


edit: nevermind, this is a non-issue.

Agreed. 30% is a non- issue. Plus, you could 'port' it...

now, sometimes I just mess with people. It's more entertaining that way. george graves

Since those are drains it shouldn't make any difference aside from being easier to plug if you were to neglect your car to the point of sludge
