i have a 350 4 boilt and i have a set of 896 off a 1966 283 with a 59cc and a set of 461 i was told that thay are off of a late 305 HO with a 57cc i was going to get the 896 cut for a 194 intak 150 ex and i was wondering if someone knew wich ones are the better head to go with on 350 thanks len.
as far as i know the 461s are the better head but i always thought they had a 64cc chamber, are they double hump heads? they also should have 194 15s already, what size valves do they have?
i think you may be refering to 416 castings, they are 58 cc chamber 305 high output heads, the came stock with 1.84 intake and 1.5 exhaust they were made up to 1982. they are decent heads, but they have limited flow, I posed the question "could i make the valves bigger?".the response was this, if you have a 1/2 inch hose and you need more water, adding a 3/4 inch hose will not give you more water because it still gotta squeeze thru the 1/2 hose .
461 heads are the old fuellies from the sixties to early seventies.thay are probably the best stock heads (with the exception of 461x heads , bigger ports)these are real rare, and still dont match up to a set of aftermarket heads .
the neat thing is, if you use the 416 ,s on a 350 you get instant 10.5 to 1 compression, lots of power, just no top end rev.good for a four wheeler, but not for speed.find an old set of 882 castings, they come 1.95/1.6 ports and can go bigger.882's are the best of the junk heads. mike
