For two, I'll take a head that everyone and their mother thinks is too "big" every day of the week and get the correct cam in and make more power every time.
A puny, choked cylinder head is a power killer. The OE heads are too small for most everything.
Again, we still know squat about what the OP has. My son bought a 360 years ago for $50 and it had 1966 273 heads on it. Seller said he did not think it had been apart.
I don't have the cc data for heads handy. But I know that the bone stock 360 head flows not so well. With 1.88 In and 1.60 Ex they are in my opinion SMALL. These RPM's are 1.71cc and 2.02/1.60 and the valves are back cut and have nicked down stems in the ports. So, in my opinion these RPM's are BIG vs 100% stock iron 360 2Bbl heads.
Putting these RPM's on a bone stock 360 2bb engine with a 2bb cam is not the best bang for the buck. A better bang for the bucks spent would to put a 75 Horse shot of NOS on it and it will not affect his cruse on the freeway. But this could easily be a BANG if the OP were to put some 250 shot pills in that system.
YMMV.
