Quick Question

Have heard here that Vortec heads are prone to cracks. Is there an area where this happens routinely? I have one I am going to take apart, it had overheated. Just trying to shorten the search and not spend money to have cleaned and inspected by someone else.

i seen more busted then not .i just machine up a 350 vortec and heads were cracked. they split thru the deck and out of the ex seat and run in the chambers .best thing is buy a new set of PBM casting there thicker and hold up better . if you did get them hot they do not take much. i have had 10 sets come thru the shop and all were junk but 3 sets

Thanks Pat!
