Is it block and head or everything. Cause I have a mrev in there and I don't want them using factory. If that's the case I have to take it off and put on the oe lower plenum.

 

Just to be safe I would put the OE one back on.

I don't believe it is the plenums as well but it's better than losing your mrev in the deal. I believe it's just the block and the heads though. I've heard they even re-use your spark plugs...

 

The long block is only the block and heads. I don't know what a mrev is but I am assuming it is an intake manifold. The long block will not have an intake manifold on it.
