i have personally used teflon tape with ULTRA GREY Permatex sealer smeared on top of the teflon tape....and not one drop of water has leaked or seeped thru the head studs....

this is the method i have used in the past with 100% reults and no issues removing studs at a later date..



just another idea of how to do it.

If they are ARP studs, take them to a buffing wheel and give them a good buffing, then try thread sealer or we have even used the brand right stuff silicon, just another idea we have experimented with and have had great success.

Resealing threads on the head studs
 
Last night i went thru removing 1 stud at a time and a serious cleaning procedure , remove the stud, clean in laquer thinner, wire wheel the threaded area, reclean with brake cleaner, use a small wire bottle brush with thinner and clean the block side hole, then goop it up with the Loctite 567 , Resealing with a high end loctite 567 thread sealer.. it will seal to 1000 psi in 1 hr - 10,000 psi in 24hrs, good to 450f .. this crap better work it was 75 bucks for a 250ml tube!!!
Tonight i will put water in and pressure test it... I really hope this works!!

Resealing worked
 
Ok 4hrs of removing -cleaning and installing and re- torqueing - put water in the system- pressureized it to 16 lbs and no water leaking from the head studs. Looks like the Loctite 567 does what it says it does.
Tomorrow i will run it thru some heat cycles..and see what happens.

Thanks for all the suggestions

oh .. and the guy who built the motor did 90% of the work ..hell the motor never made it out of the garage!.. But it was good to see someone stand behind there work.
