Due to money issues, I've got to sell my Patriot 5.3 (stage 2 heads). They've been cleaned and checked at a local machine shop and checked out fine, just need a few valves lapped. The cleaning job they did, really just got the oil off of them, still some carbon. PM for pics, etc.
They have 40,000 miles on them, springs probably need changing. I bought these when Gunnar worked at patriot, I had originally bought the cores from another forum member, bought the Manely racemaster valves (2.02/1.57) and then sent them to patriot for porting & assembly. I've still got the flowsheet and can send a pic of that as well.

how many cc are the combustion chambers? any idea how they'd perform on an lq4?

 

would definitely raise compression, hp and torque. sounds like a good deal. i would recommend having a machine shop or knowledgeable mechanic go through to ensure all is fine and replace springs before bolting on.

 

Are these still available? Can you email me at cobaltss1991@yahoo.com
