Got some Heads, Which ones are best? - Mopar Forums
Those are the correct vintage heads for a 75-80 360 81-84 318 4bbl and 75-84 truck
they may have smog holes so plug them if not using AIR
came with 1.88 x 1.6 valves installing 2.02 valves has been done before- I hope they opened up the bowls and blended- viton seals so a premium job
basically all large port heads are the same
should have hard ex seats
from stan weiss site 202 intake valve stock heads
