What Type Of Hks Hg
 

i am gonna be ordering a hks hg with arp head studs. and i want to know if i should go with 1mm 1.5, 2 2.4, 3. i dont know how to choose which one i want either lower or raise my combustion i know that but please give me some feedback if you went with one or have an idea or just gerneral knowledge to pass along. please respond

picking the right thickness isn't as important as having a perfectly smooth block .
the thickness really matters when the head has been shaved once or twice already
in order to compensate for the material thats been shaved off you add more thickness to the gasket
so if the head has never been cut before you can go with the thinner gasket . get the idea ?

HKS Stopper MHG
