We have used Timeserts to repair pulled headbolt threads on Caddy Northstar motors in our shop and GM recommends them for that purpose. Yes, Timeserts are the way to go for thread repair.

Use the threaded insert. We always use them over the helicoils in our dies at work. Much stronger and can take a lot more torque.

I'll definately ask about Screamin Eagle heads. When I had the big bore kit installed I also had a billet cam plate and new bearing and chain installed along with adding a high volume oil pump and hydraulic tensioners. That was only a year ago so if all of those parts are compatible with SE heads then it could be on my Christmas list.

You never said what motor or which head. I have a front TC 96 head that was swapped out because of very minor scratches by my ins company sitting on a bench in my garage. If ya need it PM me and we'll figure out how to get it to ya.

We have used nothing but Heli-Coil Brand thread repair tooling here for well over 2 decades.
Thousands of dollars tied up in that tooling here, in both metric, and SAE.
When installed CORRECTLY, they are a very postive repair.
Note on this, is that we've found to maintain that insert is in the hole about 1 thread below flush, on both sides, and naturally the tang is removed in a very swift action, not to create a potential problem with the last thread.
While doing contract machine work for McDonnell-Douglas, in St. Louis, Mo., many years ago, their drawings stated Mil-Spec part # such and such, Heli-Coil insert, to be installed at the original point of manufacture.
Must have been a good reason for that?
Another VERY GOOD thread repair, that we very recently used on the case studs of a 124" blower-equipped bike,(upon client request) is Lock-N-Stitch Permanent Thread Repair.
These are designed so that the more pressure the fastener recieves, the more it bites into the parent material.
Once locked in place, they are also pinned.
Mighty tough set-up.
