Is there any difference other than the cams? From what I can tell, and according the the 2AZ-FE change pdf, it appears thats the only difference. Also IIRC, the 05/06 head studs are longer than the 07+ right? So Im assuming I couldnt use the 07+ studs with a 05/06 shortblock?

 

i have 06 short block with 06 head studs with a head u sold me that was from an 07 i believe. I am actually sure all the heads are the same except for the cams. if you are using 06 block u have to use 06 studs
