What's the benefit of using the Ford valves?
If you are after larger valves, there are lots of small block Chevy valves available and you can cut 2.02/1.60 valves down to whatever size you want.
No advantages,just use SBC valves.
A lot of SBF,switch to SBC valves when replacing stock type valves,because SBC's have been bigger than SBF's,stock for stock.
