Okay, I have a B18c5 head and is rebuilt to 0miles, and was thinking about going with my stock CTR cams or should I upgrade to an after market for better performance due to my CTR pistons?? My block is also a B18c5 and I have CTR pistons in it and I'm running with a B18Ls Crank with P73 rods on it, everything is already together for the block but was wondering what Head gasket should I get to make it work rite?? And for the head studs should I get ARP Gsr or Type R?? Need Help??Anything??? Thanks
