Another point to ponder would be to get your hands on a set of well used AMG heads and give them a really good going over to see wasssssup.

I have a feeling that the best solution is to grab a set of new brand X heads, bolt them on and just run them..


The flawed GM heads would generally go 200K miles give or take.

Some cracked early, some ran far longer.

The type of usage the rig was subjected to certainly could change the life expectancy, but overall the 200K mark is a common jumping off spot for the gaskets to fail.

I had 2 used Burbs and the Dahoooley and these numbers were pretty close.

One Burb went 237 K ...The other went 267 K and the Dahoooley was a crap shoot as the engine had been changed to a Goodwrench and the bottom end failed (Main web cracked into the water jacket)


Gawd only knows what the real lowdown is on these after market heads, but the various brands seem to be staying around.

Clearwater has been in the game a long time now.

I spoke with AMG about the various parts (blocks/heads) that are on the market, and they told me that they have looked the stuff over well.

The only issues they had were that the consistency of quality was all over the map... being ...some good ..some bad and some ugly...


I wish I had more info for ya..

Good luck
