i wouldnt worry about helicoiling, they use it on full alooy blocks in the head bolt holes and other critical load areas. If it was an issue, Keith Black, Rodeck, Offenhauser, Costworth, Illmor would have either discovered it or fixed it or have found sopmething oui by now.
PS on alloy blocks and heads, early magna alloy blocks proved to be porous because of shitty quality control, so mitsubishi in adelade developed a pressure infusing system with a fancy polymer, a process that is now used world wide allowing cheaper alloy to be used in engines.
