does anyone have any link to ARP head studs for the 1uz-fe?

i heard you can use the VQ35 head studs? i know they come in 16 but i think we need 20 (10 on each head).

are the stock head bolts re-useable? torque specs? 90 lbs?

currently expanding my knowlege on the sc300 but from my general knowlege of factory head bolts, they will stretch and should only be used once. You might be able to measure and see if the head bolt has stretched out of spec but better to use new bolts.

arp head bolts are said to not stretch.

 

as for the VQ35 head bolts I dont know if they are compatible for 1uz. but the bolts are 10 x 1.25mm

Lexus states to only replace the head stud if it doesn't measure up, or if it feels as if it stretches during installation.
They do reuse them.
I have ran 17PSI on my SC400 1UZ and they still measure up OK.
I did replace them with stock Lexus head bolts with the rebuild.

The torque spec is 20 ft-lbs, and then an additional 90 degrees, but double check that, cause I'm going off of memory.
