I bought a set of 05' 6.0 cylinder heads on ebay with only like 1500 mile on them. Got them and put them on then I noticed the casting # is 706 which is an 04 and up 4.8/5.3 head. Boy was I pissed because I should have ck'd but I believed they were 6.0 heads and this guys auction claimed it came off an 05' chevy 2500 truck.

Now Im wondering if this will cause any problems and if it does what will be the problems.
I contacted the ebay member just a few min ago and we'll c if he even knows..or responds!!
Damnit if aint one thing it sthe next.
