Naf,
Make sure you mention that you have higher compression heads (I assume they hgave been milled a bit), and let them know what sized head gasket you have as that will affect how big of a cam you can get without flycutting.
That sounds like an awefull lot of lift, however I'd be most concerned about what type of lobes that sucker has. If it has a very agressive lobes (I.E. the ramp rate is very high), it will be hard to control unless you use very strong springs.
If you get supper agressive with your lift and ramp rates, then you are going to need to swap valve springs more often. If you don't put a lot of miles (er KM's) on the car then it doesn't matter as much. I'd also consider getting a nice dual spring set, just for the added piece of mind of having the 2 springs. If you do break a spring, with the duals you will usually have enough time to pull over and shut the car off before the engine eats your valve ($$$$), whereas with a beehive single spring, the valve gets chomped ASAP.
If I were you I'd consider working with Partick G over on LS1TECH and have him spec out a custom ground cam for you. You can get the grind done by Lingenfleter (since you know someone there) fairly easily. They ground mine for me. If you get a custome cam, you can get exactly what you want. Especially given that you want it to be 'different' but not also scare away every girl in the area. Just tell Patrick what you want.
Glad you came around to the idea of getting a cam
