i know but i was talking to a guy that builds the engines for cars at our local short track and he thinks i would be ok with 1.94 for street use he thinks 2.02 are for more strip car rather than street

The 1.94's are better for the street. You won't see any gain unless you'll be above 6500rpm most of the time. I'll bet that cam and your springs are done by then anyhow.

The only ones I can think of are the LT-1's that came in Z-28's and Corvettes in the early '70's that had solid lifter cams and some compression.

Sam, refresh my memory. What vehicles had these engines with these heads. I am getting old and forgetful. But those years all seem to be smog engines that were lucky to make much over 200hp.
