There are other ways. All it took on Leo's engine was to buy a set of AFR SBC heads, cut them, weld them together, re-machine all gasketed surfaces, have custom head gaskets made, fill the deck of the block (pinned), transfer the new bolt pattern and coolant passages, then redrill everything. Then deck, assemble, etc. Then to the backup engine. However he does run low 9s on methanol and a single turbo with it.
