I'm running a set of 452 iron heads on my motor. Years ago, I removed the end exhaust studs on both heads (goes into coolant passages) for header clearance (big tube Hookers, which I no longer have) and used header bolts with RTV on the end stud (now bolt) holes on both heads....worked for years. Now, I've developed a small coolant leak on the passenger back header bolt. I've tried to re-seal it 3 times & no amount of RTV will seal it. I "think" the standard SAE threads in the cylinder head have worn & are "sloppy" (not yet stripped, but getting there).
How do I fix this short of removing the head?
I've considered draining half the coolant, unbolt & pull the passenger header back, scrape off all the old RTV, degrease/dry with carb cleaner & install a factory exhaust manifold stud in that hole with some epoxy? Does anyone have a better idea? My local exhaust shop won't touch it. THANK YOU!
