Help with heads or cam id? Hey guys I have a 02 ss and the previous owner said it had a small cam and heads. The right bank head has " Thunder Racing PO # 60955" does anyone know what that means? It made 363hp when I had it tuned. So I'm wondering are they ported stock heads? Or something else like a cam? The numbers just seem low if it really had h/c. Btw the previous owner said he did not know the spec on either and that the guy he bought it from did the mods. The car just has Slp long tubes, duel duel exhaust and blackwing air lid. Numbers just seem high for the mods.

Don't worry about the numbers just yet. Many possibilities, and dynos vary 
Is there a three digit number on the front of the heads (mine is on the passenger side) towards the front on the car?
