Head Studs 120-130

posted by  someone claiming to be Fiorano on  Fri Feb 8 06:02 CST 2008 [RELATED]

I understand the head bolts are good and excellent at doing their job-
but i have a new racey motor and would like head studs.
i saw a picture in a read only thread- a b20 with porcupine look of head studs.
what are the specs?
as ARP told me they don't have a kit.
any help?

Yeah...ARP doesn't say they're for Volvos. A friend of mine has been selling them off and on on eBay for years. I believe his eBay id is iadr.

I run a tap down all the holes to clean everything out then torque them at 70. Dick

thanks very much
do i follow the haynes manual torque step- is it 70 straight or incrimental?

i imagine i would do 70 ft. lbs warm it up and retorque and break in the cam (15-20 minute varying RPM 2-3.5K?)...then check torque specs again...

then put in the double valve springs...and go beat the car silly?
