Is this a good head set-up?

I have an opportunity to buy a pair of heads for my 69 with 351w. I'll be using this car for street/weekend cruiser. My question is, is this a good set-up? Here's the specs on the heads:


a pair of cast iron heads from World Product. They are Windsor Seniors.

Specs as follow:

Valves: 2.020” X 1.600” Manley Street – flo forged steel

Valve Locks: 11/32” X 7 degrees Hardened steel

Valve Springs: 1.250” single, 1.750” Installed height (double springs……..1.440”)

Valve seals: Iron, umbrella style

Valve guides: Iron, Integral steel

Pushrod guide plates: Hardened steel

Rocker arm studs: 7/16” top X 7/16” bottom

Combustion chamber is 64 cc

Intake runners at 200 cc volume

Windsor flow # : @ 28” h20

Is $550.00 for the pair a good price?
