The 351W is most likely your best bet, If you want a big block go with a big block not a small block that is just as heavy and exspensive as a big block. The 351C 2 valve heads are good but with so many new heads for the 302/351 the technology has really gotten alot better in comparison the 351C heads although good are old tech at least 30 plus years. The 351C 4 valve heads have ports that are just to damn big for anything but 7000 rpm road racing. So i guess either a good 351 setup or a 460 setup are the best bets.

Here are some weight for ya, long blocks, all iron:
Cleveland 550
Windsor 510
FE 650
429/460 640

True true about aftermarket windsor heads being better than the old cleveland heads, especially the exhaust side. But for 350 ponies he won't need aftermarket heads. Now if you are compairing stock to stock, then the cleveland wins hands down. If he did go that route, there are some excellent aftermarket cleveland heads as well. The 4 valve heads are overkill on a street motor. But they still work very well on a street motor that is set up for them. I have 90% of peak torque from 2000 to 5600 RPM. The 460 is the Clevelands big brother (some parts are interchangable). But it is a BIG one and can be a packaging issues at times.
