just heard back from Joe.. cams/tensioner/water pump aren't seized... the timing belt stripped at the teeth at a section.

he won't be removing the head till friday so i won't find out till then but most likely cause was a bad timing belt batch coupled with dual valve springs

bad news is all 4 exhaust valves are gone as per your hunches... hopefully the cast pistons survived.

looks like the heads coming off either way.. may as well dump in flat faced exhaust valves at least and maybe the Toda belt...

dual valve springs were Toda A's though.. didn't think they were that much more seat pressure than ITR duals???


now i know what you guys are probably thinking.. i wasn't thrashing when it happened.... weird
