I bought a car that came with a pair of patriot heads. I would like to know a little more about the heads but cant seem to find anything. I know people have mixed emotions of the patriot heads but i would like to know if anyone has or had a pair with the number 4468 stamped on them. Any info would be appreciated. Also, i already called promaxx and they said they couldn't go back or find anything on them.

 

You'd need to measure the intake valve and that would probably tell you if they are stage 1 or stage 2. Not sure of the difference between stage 2 and stage 3.

 

Do you have pics of the stamp # . To determine if they are stage 2 you need to measure the valve 2.02 = Stage 2 Patriot did not leave the casting # on the heads , so would want to measure your Combustion chamber also .

 

The previous owner doesn't know?

 

No, the previous owner didn't have any info on them.

I will have to measure the valves and go from there.

i appreciate everyones input.

 

 

They did offer a 6.0 heads with welded chambers for High Compression ..... but the basic offering for 6.0 heads was 68cc 70cc and 72 cc and their preferred casting was the 035 die cast
