350x head problems

[yaegerb]

GeeDangit! Tap snapped off just gonna throw it back together and calk the leak. It's cheap I know but my patience is wearing thin. It'll blow up in the next year or two maybe then I'll completely rebuild it with the new head. It's exhaust stud threads are boogered up from the last owner, but he graciously included a NOS head when I bought it. Thanks for the help guys!

you serious clark?......

350X heads are NOT cheap. they run starting at $350 minimum off ebay. you may think twice about that....

86-89 trx350 head is a direct swap. They're much more available and much less costly.

This is getting so complicated that it’s difficult to follow. Seems like you’ve got drills, taps etc broken off in the hole. My idea; heat the area with a torch warm enough to anneal the broken tools. You need an absolute rigid clamping so nothing can jump, jog around. Best bet; a vertical mill with proper clamping tools which won’t jump around. Your parts are annealed enough when they lose their magnetism; at this point the parts should be soft enough that they can be more easily removed. Using a center cut milling cutter you can plunge cut thru the broken parts.

As far as drills & taps go; you can use a taper tap, plug tap or gun tap to thread holes. The thread depth goes in % of thread depth. 50% to 75% threads.
The point is that there is a lot more to this than just going to a tool store to purchase drills & taps. Do you take this to a machine shop, I’d recommend it.

Got it all put back together. Cleaned the headers and exhaust port. Helped a ton, it had an insane amount of carbon build up.
