Toooo! tight engine

351w w/cleavland heads
Can't understand it! The build up of the engine was to spec.

ENGINE HAS:
CLEAVLAND 2 BBL HEADS W/STAINLESS VALVES
COMPRESSION 10.7: 1
HYPEREUTECTIC PISTONS CLEAVOR STYLE DOME .40 OVER
ROLLER ROCKERS ON 7/16 STUDS
LARGER PUSHRODS 3/8
CLEVITE 77 BEARINGS

THE ENGINE IS VERY VERY TIGHT

I HAVE TO USE A BREAKER BAR TO TURN IT OVER

I'VE DOUBLE CHECKED THE CRANK AND ROD JOURNALS
AND BEARINGS MATCHED (ALL WITHIN TOLERANACE!

CHECKED THE RINGS TO SEE IF THERE WAS A MISMATCH (NOT)

CHECKED THE RING END GAP TO MAKE SURE NO BINDING (NO)

THE CYLINDER BORES ARE GREAT AND THE PISTON BORE TO PISTON CLEARANCE IS GOOD?

WHAT AM I MISSING? WHY IS IT SO TIGHT?

HELP!!!!!!
