1. I HAVE A B20B BLOCK WITH A GSR HEAD, WHICH HEADGASKET DO I USE, A GSR OR B20?

2. I CAN'T FIND A PART NUMBER FOR ARP HEAD STUDS, THEY SAY B20 WITH B16 HEAD ONLY. I HAVEN'T FOUND A PART NUMBER FOR B20 WITH B18 HEAD.

THANKS FOR YOUR HELP.

 

use a stock b20 head gasket

 

use b20 head gasket, and for head studs or bolts....use GSR
