Topic: carbon build up on 22R head bolt??

[Tombo-4Lo]

 
Well I pulled the head on a 22R. On the the exhaust side, the second bolt to the rear was difficult to get out. This bolt sits between #3 & 4 exhaust ports. The threads & most of the way up the bolt is clogged with carbon. Could this be a cracked head???

your fine,  justclean it really  good,  make sure  the block is cleaned out really well also,  oil is pushed up thru the headbolt galley  to the camshaft,  so make sure its clean
