Greetings,

i have got a set of heads from PRC from a friend of mine, and he does not know the specification of the heads.

the numbers on the heads are 7138101465892 and 7198v5134776

can anyone help identify what heads are these.

regards

Look for an engraved number in the rocker area of the head. Then give them a call with that number.

No there should be a hand engraved number somewhere in that area of the head.

I did the same thing I bought a used set the only way to tell is by getting the hand engraved number from under the rocker arm pedistal Idk if its on both heads or just one. Then call texas speed they work better that way trust me lol. You can barely see it in the pic because its so fine and the flash hid it. I believe it was a 5 digit number.

Can you measure the intake valve size? 2.02 would be a stage 2 head.
