Gut new bolts, gaskets etc., picking up the head tomorrow mate, im interested to see how it looks.If your head gaskets were black, your engine hasn't been apart before.
BUT, as your post is "9100 mile Rebuild", I'm assuming it has.
The head bolts are good for 3 or maybe 4 pulls but that's it.
Replacing them might be an option.
Looking goodthis may be better.
