I'm gonna be switching out heads and timing belt etc..... but i was wondering if the h22a and h22a4 arp head studs are different, i have a '99 h22a4 and im putting a '94 h22a head on it that was freshly rebuilt, now this has been done before, what studs did you guys use cause the h22a ones are about $40-50 cheaper than the h22a4, i dont get it..?????

 

anyone?

 

I think there is only one type of ARP studs for H22...
AFAIK all the H22 heads mount the same way.

 

They should be the same..
