BenKey Posted March 15, 2006 Report Share Posted March 15, 2006 What casting are they? What is the size of the combustion chamber (cc's)? Link to comment Share on other sites More sharing options...
tawss04 Posted March 16, 2006 Report Share Posted March 16, 2006 They will bolt on and work, may need some tuning. The LS6 head is the same design as the LQ9 heads on the SS but with a smaller combustion chamber, so you are going to raise the compression ratio. Idont have the book with me that has the specs. A friend of mine is building the same engine only cause he has a SS engine and a set of Z06 heads and cam sitting in his garage, he is going to put it in his 99 Silverado.

Quik Posted March 16, 2006 Report Share Posted March 16, 2006 243 casting is around 64cc 317 casting is around 72cc both flow the same and have same valves you would gain HP from compression and it would be around 10.8:1 so possibly a net of 20hp from the gain of compression Link to comment Share on other sites More sharing options...
