I've used SCE copper head gaskets on a lot of roots blown Mopar motors as well as on SB and BB blown Chevy motors. On your deal I would have the block and heads machine for receiver grooves and use steel wire O rings on the block or heads, your choice and receiver grooves on the other parts
I've been able to reuse them several times after they have been raced ad driven on the street, you must anneal them each time before using them to get them soft again so they reseal good and properly
SCE makes them in several different versions for blown motors, talk to their techs to see which ones they recommend for your deal. 661-728-9200
I'm going to use them on my new heads up no prep B1-MC crank driven supercharged motor on E85 with north of 30 Lbs. of boost, hopefully they will seal real well on that combination
