The head has never been off of the car, so yes, the bottom end and head are untouched. As mentioned though, the car has a set of Kelford 272 cams and stronger springs w/ titanium retainers.

The exhaust manifold is ported, and gasket matched to the exhaust side, which is opened up a lot. It was ported by studderin, a very well known porter in the gtp / ls1 community. His work is simply amazing.

I am running the stock wastegate, with the stock spring pressure.

I run a Tial BOV on my Buschur piping.
