redmt, there's usually a parts misalignment....LOL
As Lippy says, if all the parts come from the same place, they usually fit together. When you snag heads from one vendor, an intake from another vendor, a block from another vendor, then you have to cross your fingers that it all plays well together. Most of the time it doesn't.
I rebuilt a 428CJ for a GT500 restoration a few years back. The cast iron intake came in at 78 lbs. Fun stuff.
Was working on my customer's 289 today and found out that Ferrea sent titanium exhaust valves with hardened tips, when they should have been short and used lash caps. They also cut them with a square groove instead of a radiused groove. Just the exhaust valves ran $800. They screwed up, so they're eating it. However, I'm another week away from assembling the heads, which puts me in a slight bind.......SOOOOO..............
I washed and painted Chris' timing cover and the goal is to have the timing cover,
oil pan, and some other assorted goodies mounted tomorrow.
Oh yeah, pushrods came in too.
