Found a good deal on a set of these. Is the Summit valve decent quality? Will these Chevy valves work in a 2.02 J-head?

Obviously the diameter is smaller but that isn't a problem if the guides are being redone anyway? Smaller diameter should help a little with flow.
The length work OK with .500"-ish lift cam? They are 4.911" long vs 9.810 for a stock SBM. That shorter length would be my biggest concern.
My '71 J-heads should be gone through before they go back on and these valves are almost too cheap to pass up.
