i just recently put my head back together on the gsr block, b16 head and gsr arp, i torque them down to 63 but i think they have to goten loose because im geting a litle leak where the gasket separates the head and block, please help is any thing messed up, i also have 1 dowl pin is that the problem

 

well you torqued them down to the specs but did you use ARP moly lube or just reg motor oil? if you used motor oil the head studs should be torqed again after 500 miles... someone might have another imput but i have seen a diffenence on using the moly lube than reg oil

 

Did you check the block and head mating surfaces for straightness ? And why would you put the head back on missing one of the guide pins? The head studs will somewhat line it up correctly but the dowels hold it dead on....I would take it back off and get the dowels in and have the head surfaced and get another new headgasket....dont use a previously torqued one. just my opinion
