how much boost and horsepower can you have on a stock bottom end and stock heads before you need o-ringed heads? I dont want to blow any more head gaskets. Ill be pushin about 10psi with my A-trim.

You do not need to ever o-ring your heads when using a stock block. As long as you have ARP head studs, good gaskets(felpro 9333-PT1 or the 8548-PT2) and a good tune you should not have any problems. If you were to step up to a racing block and 15psi+ then it would be wise to o-ring the BLOCK.
