building a lsx block 4.185 bore 3.62 stroke 398 for the street race class in the nmca but many people are telling me that i better bring a head gasket for every pass if planing on spraying the 98 jet with a single nozzle with progessive controller

what do you guys think will be using commetics and edelbrock heads and a flat top piston

tire limited to ET street

will be using stock bolt pattern heads
