I am looking for techniques to increase valve lift on our L67 heads. I would like to run the Intense Stage 2 cam with YT 1.7 rockers for a total of .565/.575 lift. My machinist is already rebuilding my heads as well as a P&P job but he is not familiar with these heads. I'm trying to explain to him but he giving me the "just because someone said on the Internet" response. So, can someone explain to me how to explain to him where to make the cuts and how much?
Just tell me what other info you need. The heads will have the ZZP modified retainers, SS valves (intake enlarged to 1.9), ZZP modified retainers, 105# springs, Viton seals, P&P job (gasket match), and hopefully cut for S2/1.7 valve lift.
Patiently waiting for the gurus...
