I have run flat tops pistons with old 461 double hump heads on 350's and 383's and a thick head gasket on 87 in the past but you cant run a lot if timing. I forget the details as my brother built it for me but it was a daily driver and remember i would add timing and run 91 octane on ocassion and it really woke up! I later switched to 64cc brodix track1 heads and it was alot more detonation proof due to the heads dissipating the heat better.
