As some of you know, I recently lost my (second) cam shaft drive gear to walk or something....moment of silence...
Anyhow, I was thinking if the internals are good, I'd install a new cam and lifters, button her back up for break in.
BUT, I'm having one of those "since I have the engine apart anyway..." moments. I've already got the peripherals, DD duals, double 2bbls, good exhaust flow. I'm changing the cam anyway, so I could go a bit more aggressive, but, as I understand, the head would need work to reap any benefits of the cam upgrade.
Who might I go to/ship to, to have larger valves put in my head, shave a bit more off maybe, porting and polishing work? Does anyone in the SF bay area do this, have time to do this for me? Are there particular machine shops you all use that do this work reliably for SL6's? I simply don't have time for the porting/polishing work, nor am I qualified to machine/install bigger valves.
Particular note, do people upgrade/modify the valve springs, rockers and/or pushrods when they do this typically, or are those typically not part of the picture, i.e. I could use stock ones that I have?
thanks all,
Brian
