tubman,
'52 Olds Rochester jets size primaries 51's secondaries 56's
Extensive trials with my A/F meter showed the motor.......274, Max-1, 8to1 comp,
sbc/8ba dist.........was happiest once I plugged the power valve. I tried different combos of jets and bringing the curve in earlier and later but settled on the above.
The motor pulls hard to 5000 rpm any time I ask it to and can easily outrun the
brakes and suspension and most any flathead in my area. Most any, not all.
SQUISH
The BEST head gaskets I use from VanPelt are composition and squash down to .040.
Yikes......save your $$$$$ and further frustration ,shim style gaskets will find
leaks you would otherwise never have. Humor me and do the grease thing, I usually
take 6 to 8 hours to do a head but I start knowing each chamber will require full recontouring and I use only iron heads. By your description I think you'd be looking at maybe 8 hours to do both, maybe even less. Doing this way you know you have .040 over each piston once the BEST gasket are torqued....plus you now have what I believe is maximum street compression.
Be reasonable.......see things my way.
Best of results what ever you do !
