To answer your question directly,yes a head swap can raise the compression ratio,but all for not if the rest is worn like a engine that old would likely be.
yes and thats is were the flat top cast pistons can come in to play with what . decking the block will help and many sbc have very bad deck s for finish older sbc not bad newer ones can be bad . that is why i really do not care to post any thing any more anywere. i do not build engine for sound or buy smaller CR chamber head just to put bigger cams in for more sound . for me it,s the parts all working together to give the best output at the RPM range were the engine will see use. now i must go warm up my shop to work on some engines built for power
