hello all<br />i am currently rebuilding 69 rude 55hp. my inner exhaust cover is pitted pretty bad. both sides of my cylinder head have some slight pitting.would prefer new parts but can not find anywhere.would filling in pitted area with jb weld and resurfacing work? also i notice every piece of motor including inside of cylinders was painted. can i repaint with a high temp engine paint?<br /> thanks for any info
