418 Stroker options....

Ok so I did some calculations and I am thinking of stage one I will get a forged stroker kit with -21.5cc diamond pistons and use .027 cometic MLS head gaskets to get 10.2:1 compression with 65CC heads. Then stage 2 will bring a 671 blower kit at 8 lbs of boost using 0.12 or 0.14 cometic MLS head gaskets which is about 8.35:1 static and about 12.5:1 dynamic

so here are the questions: I have never run such a thick gasket and worry about it in a boosted application, what do you think? since the CR will be a bit high, I have 94 octane here and I am hoping that I can find a head with a helpful quench to keep my octane requirements down else I am running water meth....

what heads would you recommend? are eddies a big gain over the knock offs after a blower is introduced? and single or dual plane intake for stage 1?

thank you all!!
