i think my shop charges $400 to o-ring or fire ring a 6b head, but from what they say it's better to go with o-ringing if you are going to stay under 70 psi. i would get studs right away if you go that rout. just dont forget to hot retourque the head studs. one of our customers blew out his head gasget after we o-ringed his head and tryed to blame us.... long story short he didn't read the directions for the studs and "forgot" to retourque them hot. just throwen that out there

yea we have a special jig for the head that centers over the combustion area, and you need to make sure your depth is right, we surface all the heads to make sure they are flat or you could get hi and low spots, i would be very carefull when you try, i have a junk 2nd gen head we peacticed on first, took 3 holes till we got set up right, but once we got it, it was a breeze. just proceede with caution, i don't want to see your head become scrap metal
