    Rated 5 out of 5 by from I bought a set of these heads for my 82 6.2 diesel after spending many weeks looking for a new reman head for a 6.2 that addressed the common cracking between valves and I came across these and even though they say they only fit 6.5 diesel They fit my 6.2 really well. Only trouble I had with them was one of the spots where you bolt the intake to the head the threads were messed up in the head so I had to re tap the head to get it to work but over all I was very pleased, they were packaged good, no rust on them when I got them.

    Rated 1 out of 5 by from Early Failure Have less than 10k miles on these heads. Have had a ticking noise shortly after installation. Finally removed head and took to local machine shop. ALL the Guides were beyond spec. Valves were not sealing correct due to valve movement. Would not recommend these to anyone looking to get good life out of these parts. Now spending over 800 to get heads in good order.
