Will have to measure the "quench" again to be sure when I mock up the engine, shooting for .40 to .60 seams like the optimal choice. I will use the necessary gasket to achieve that.

Using the powerglide was more of a convenience because I know very little about engines, but I know a lot less about transmissions. That said, I have a lightly used rebuilt 700r4 (about 500 miles) being delivered this weekend from a friend of mine who totaled his car. Got a good deal on it so, i'm jumping into it.

I would rather not do any additional work to the vortec heads, ie... cutting the guides and the stud base for guide plates. Looks like making the 700r4 swap will be money better spent.

Should I stick to the 268 cam with the 700r4 now in the loop? I keep hearing .475 is max lift, does the fact that I have screw in studs help this, or is the clearance issue on the valve guide height?
