When I pulled the head on my 12ht last year things did not look too bad ................but when the pistons came out ,well I have never seen rings like it ,broken ,stuck ,ring grooves worn to twice there normal width and the bores are worn into barrel shape wider in the middel than top and bottom.So when you have the piston out make shure you mesure the bores top middel and bottom or you could be wasting a set of new pistons and rings.
