those heads look like they were run with the wrong antifreeze or the PH was way off on the mix. I have had a buddies set of heads off of his motor so we could slide a new 500 inch short block under them and there was no marking at all. Are those your heads or are you just saving the pictures so you can be part of the hater band wagon


your joking right? 5000miles NO WAY those heads should be looking like that. don't care if your running pure vinager.
if you look closly at those head pics its obvious that thats a casting issue. quality control was bypassed that day.
BTW what is the correct PH balance of antifreeze? all this time i thought it
was either 70/30, 60/40, or 50/50 mix. now its PH balance...
attached is a cylinder head with 80+k using the "wrong" antifreeze.
