318 MRL Stroker

Ok I found 2 different sets of:
EQ heads with LA Intake pattern
1.920/1.624 Intake/exhaust valve size. 172cc/62cc intake/combustion and max .480 lift

Next set:
Monster magnum-STAINLESS 2.02 INTAKE VALVES AND STAINLESS 1.62 EXHAUST VALVES.
62cc
Max lift of .600

the MRL motor "I'm guessing" has close to the first set I posted.

As Mike said they were basic stock heads with very little done.
And low lift so I had a couple of cams to choose from and no reliefs cut in the pistons.
