How much head do you need?

Cylinder head flow for the crane 693901 camshaft?
1.78 & 1.5 valves good enough?

I wouldn't get too worried about head flow; that is a very mild cam, only slightly larger than a stock 360 2bbl cam. Years ago I put one into a 1965 Hi-Po 273 that also received a set of 302 heads, worked out very nicely. Go for it!

"Goal is long distance driving"

how about some stock 273 heads, they'll meet the goal

That is a loaded question.

That's an excellent cam for lo compression engines...even 340, for street driving.Tons of torque, smooth idle, pulls hard and gets excellent mileage.
Not a quarter mile piece.All but the drag racers will like it.
