Head gasket woes
VACUUM ADVANCE IS NOT NEEDED, RUN 34 DEG TOTAL TIMING @ 4500 , USE 1008 FEL FRO HEAD GASKETS. RETORQUE HEADS AFTER 30 MIN RUN TIME. NOT SURE WHICH HEAD BOLTS YOUR USING, MOST ARP. BOLTS TORQUE TO 100-105 FT. LBS. IN SEQUENCE.
REMEMBER THE SMALL BLOCK MOPAR HAS ONLY 4 HEAD BOLTS.
IF YOUR BLOCK OR HEADS HAVE MORE THAN .060 OFF, EITHER ONE THEY WON'T SEAL.
JUST MY 2 CENTS.
