The Truth on 305 Heads used for performance! | Hot Rod Forum
2011年5月7日 · 416's and 601's (early/mid 80's 305 heads) are about as close to a performance head as you'll get on a production car from that era (the other heads used on 350's were pretty much junk, even the vette aluminum heads aren't significantly better), and can also be used well in a high efficiency, low end/mpg setup with good effect.
Learn me: Cheap 305 power upgrades! - Grassroots Motorsports
Set of used 305 vortec heads from a 1996-1999 305 pick up or van. DO NOT USE 350 heads on the 305!! You will need a different intake to match the heads, not too expensive through jegs, etc around $125-150. To make best use of this, you'll need a better cam too. Luckily the small block Chevy is the cheapest thing ever to build up.

305 marine engine - Hot Rod Forum
2007年3月11日 · Same block, 2-bolt mains, same crank, rods, pistons, the works. The marine cam is probably in the neighborhood of 202/213, ground by Melling. Heads are possibly 309 and they are direct copies of a normal, low-po, 305 street head. Almost all 305 marine motors fall into the 180-220 hp range.
