Anyone done anything besides the basics to GEN II heads (3 angle valve job, port, polish, higher rockers (1:9 ratio vs 1:6 ratio).

Twalt, who makes 1.9 ratio rockers? and how much are they? I'm very interested in changing my rocker arms on my 3.1MPFI(no turbo :( ) but I am planning on buying a TGP sometime this week!!!!!!
Thanks for the response.
Several people make 1:9 rockers. Put them on my blown 3.8, and was truly impressed with the top end gains. Should work the same both motors operating with boost?
