Question opinions on Liberator o-ringed heads

Hello,

Like the subject says... I need to either rework my heads, or buy reconditioned from Ford or I was looking at the Liberator heads. Anyone have experience with Liberator and/or Liberator o-ringed heads?

Thanks in advance.

Stay away from the o-ringed heads. They are nothing but trouble. Most folks that were doing them have stopped.

They've had a tough time getting them to seal correctly with the 6.0 and overall aren't worth the hassle. What is the need for these. The stock head gaskets are holding plenty of power.

with a flat engine surface and a flat head. as well as making sure the heads, valveseats etc are not cracked. you shouldnt have a issue. just make sure you get a new oil cooler. oh yeah arps. from whative read and or been told the issues with orings is that if you do end up with a issue the heads and even the block can sustain damage and be more costly in the long run. if the same place that cannot get regular head gaskets to work my guess would be adding fire rings/ orings would just magnify their incompentence.
if for some reason the stock gaskets are not holding and the surface, heads are all flat then i would look at driving habits, tuning and yes the oil cooler to see where the oproblem is comming from.
