well i hear good things about the hg...mhg right??anyways im kinda on the same boat wit u as far as hg choosing i hear the stock hg on the sr can hold about 300hp thats what i get from our fellow niconauts i think the only diffrence between mhgs are that the comtec is a american product and the nismo and apex and greddy are all japan stuff,im interested to see what kind of answers u get ill keep posted

<=== apex'i

1) HG torqued about 5 different times.2) Still holds wonderfully fine3) A tab that sticks out between the head and the front cover that says "APEX" = DOPE!!!

i have a cometic metal head gasket and arp head studs, it is holding up really well....i seen some reviews on it like 4 months ago and i remember it saying it should be good for up too 35psi + ......so u shouldnt have a problem with it at all...

stock headgasket holds fine if you know how to tune. im running around 350whp on the stock headgasket with no problems. Detonation and Overheating (poor tuning) is the cause of the stock gasket blowing, not the boost pressure.
