I was torquing down my Champion Heads and pulled the threads out of the block on one hole. I had to remove head to repair. Block is at machine shop. Can I still use the gaskets or do I need to get new ones?
The reason I would not re-use them is that they are Lipped and once used they are flattened.
SCE in the other hand are flat and I have re-used them more than once.
Matter of opinion..
Good Luck!
