With flat top pistons on a 350 engine I would not think you would have too high of compression to cause this problem, unless you have heads with small cc chambers like 58. Going to 64 to 76 cc heads would lower the compression.

Camshaft duration could effect dynamic compression some too.

Are you sure you do not have excessive ignition timing?

Does your distributor have mechanical and vacuum advance or is it locked out? The advance curve may be too quick.
