Pro comp head failure

Yep it could be done.
I'd rather scrap the junk heads and buy a decent head rather than having the expense of repair. but it's not my decision.
Good luck with whatever you choose to do.
Except in his case, you have the cost of the heads, then the cost of the porting he allready had done. So probably would be 2500-3000 to replace with a fully ported new set, as compared to less than 1000 to weld, re machine, surface and replace all the worn parts...
