Weird - the center bearing surface on the cap looks the worst...would not have suspected that - would have thought the furthest right would be the worst. Almost makes me thing at some point prior to this adventure - the center 2 bolts on that cap were overtorqued.... I agree - work with what you got, if the head does go - there's usually plenty on ebay to be had for a decent price - just gotta be real sure you're getting a good one. For the 30 bucks it costs - buy another timing chain, who knows what kind of weird stresses acted on the old one during this! Make a list - check it twice - not because it's Christmas but because - if you work off a list of steps that you have to perform and inspect and check off - you tend to make less mistakes.
