Oversize valves?

Thanks for the info. I forgot to mention that I already have a set of the 1.70/1.44's that I have had for years but wasn't sure if anyone was using them with stock bore. Just trying to see what setup I could get by with on the cheap with what I have. I had also heard of some using the 300 Ford Six valves.

I guess the plan was to run a stock bore/basic re-ring/new bearing type engine with a nice head on it. That's what I'm thinking so far anyways.
