Are there 2 different size heads on the G54B? I bolted the head down, lubed up the cam and dropped it in, then dropped the rocker shaft assembly on it... only to find the rear two bolt holes missing, and the back of the head is flat, rather than angled. The valve cover won't seal on the head, either (I dropped it down to look), since the cover arches to the rear, yet this head is flat.

I'll be checking with the guy I got the head from tomorrow, but it looks like I'm going to have to either salvage my current head (not sure if possible until I pull it from the old block) or just bite the bullet and spend another $400 for a complete reman head.
