It does give gains. Untouched, the gmpp exhaust manifold was tested to give about 4 whp & 6 wtq.

Mine is ported though.

I have a 3 day weekend coming up.

I'm going to start tearing her apart this upcoming Monday. I hope to have the stock head off the car by the end of the day.

I need to order a new valve spring compressor tool (sold mine last year), and then I will transfer the supertech springs & cams over to the gmr head.
