I run the steel core Fel-Pro's. Absolutely no issues even with blazing EGT's that high boost and a low timing pump gas tune produce. I retorque them after the first two heat cycles (they barely move) and they don't move after that.
Never had good luck with the Pearcy's aluminum gaskets or the copper ones, tried them in the past. Been using the Fel-Pro's for about 3 years now with very good results. I use their steel core collector gaskets too.
