Has anyone heard of someone using helicoils to rethread their block? I know helicoils work really well for low-torque applications but will they hold reliably @ 60 lb/ft? I think i may have stripped out one of my block threads putting in my arp head studs. I need a reasonable solution if this is indeed a problem. Any suggestions would be greatly appreciated.

Helicoils suck. Use a Timesert or equivalent.

 

you will most likely have to take the block up to a macghine shop and have a timesert installed. Helicoil is strong and can hold torque over 60 ft/lb but I would DEFINATELY never use it for head studs/bolt holes. In my opinion I would suggest that you take it to a machine shop to get it done becasue it sounds to me like you are not too experienced with installing timeserts or helicoil. If you do it wrong, you just ruined a block...

Yeah, they hold torque, but the ******* like to back out with the bolt upon disassembly.

 

that is why if you helicoil something you put locktite on the helicoil and let it dry completely before assembling

 

I've used a helicoil on headstuds before, not a honda block, but I know it will work..

Your right, ive never used a timesert or helicoil in a car motor. I use them alot in kart racing briggs motors, but none of those are recessed. Those motors are also torqued in in/lbs nowhere close to 60ft/lb.

would it be wise for me to go ahead and put the head on and torque it just to see? I am not positive that i stripped the threads.

I have no clue what it would cost at the machine shop to get that rethreaded.
