I'm sure this is a stupid question, but I live by "it never hurts to ask." Does anyone know if the cylinder heads on an 08 align with the 2000 model? If they do what are some potential problems? I remembered reading somewhere that the cams could swap over but there could have been a potential issue with valve clearance.

 

I believe they do align, but things are pretty different outside of that. The 08 has two spark plugs per cylinder and the pistons are domed with recesses. So you'd probably need to replace the pistons to avoid beating up the plugs and maybe the valves too. You'd also need to replace the tone wheels as yours has 16, the 08' has 32 teeth. Also the computer would need to be replaced. I'm sure there's more that I'm not thinking of.
