You need How To Rebuild Small Block Chevys,
I forget the author but it had a mechanic on the
cover putting an intake manifold on a small block.

I rebuilt 4 of them using it and never had a problem.

What lifters do you have and how did you adjust them?
How long did you run the primer?
You did remember to install all the oil gallery plugs?

Basic oil flow in the small block is
Sump
Pump
Filter/bypass
Mains/rods (through the crank)
Camshaft (oil comes up from the mains)
Lifters (through the oil galleries on either side)
Pushrods
Rocker arms and valve stems
Drain back into sump from all the above (drain from front camshaft
bearing lubes timing chain)

Hey gshafer, pay close attention to Steve W's list above--I'd guess you
oughta look closely at one particular area I've seen problems in
lately--Steve's "Filter/bypass" reminder! Somehow those early 327 year
engines cause basic misunderstanding of what goes where, and lately I've
seen several so-called "factory-rebuilt" engines with parts omitted. s

Seems that I remember that those oil gallery plugs (Welch type) could be a
weak spot as well. Racers often threaded them and installed pipe plugs.
