First off, there is no need for a MHG for the n/ a . The reason the HG’s went out is due to the low torque spec on the head bolts . A MHG is for high hp numbers and not an n/a capable of way less than 300hp at most. And $200-450 is probably not going to cut it for parts and machine work on the head. The main things to insure a good long lasting head gasket are:
· ARP head bolt or studs(preferably studs)
· Clean and chase the threads in the block
· Copper Gasket Spray
· Make sure the head is with in spec before re installing
