how do i id a set of chevy sb heads ?they came off of a 350 or so thats what i was told. i actually heard the engine they came off from run and it ran well.i bought a sb350 .030 with flat tops and i think a stock crank.the motor is just that the block crank and pistons.i got a pile of extras with it like a set of heads that the dude said came of a 350 4 bolt?? i got a weiland single plane high rise and a factory aluminum 4 barrel intake from who knows what. Block #s are14093638 i cant find the outhers yet do to nastiness all over the block.got it all for $100.what i would like to know is how do i identify these heads they have straight plug holes if it helps.

Pull a valve cover and look for the casting number,it will be similar to the block number or something like this 14022601,then just look em up on one of the many
chevy websites.

Type mortec in your search bar they have all chevie motor numbers identifacation by casting numbers. Francis

thanks guys, they turned as# 3927185 69-76 307/327/350=70cc chambers,next question is are they any good for the #14093638 .030 87-95 350 4 bolt?

What kind of Build are you looking to do ? Mild Street or street / Strip ? And for heads what cost Budget are you on . The single plane is a no go for a 355 street car . The 2800 stall will work well . What rear end will you run in that car ?

Not to hijack your thread- but I just discovered a set of 186's on my 327 in my streetrod. Are these still a good head? Yes they are 202's- are they worth much?

Yes they are . They are the Late Fuelly heads with the bolt holes in the front . Chevy used them on 1969-70 350-300hp with the 1.94 / 1.50 valves . And on the 350-350hp-370hp L-T1s and the DZ 302s with the screw in studs /guide plates and 2.02 / 1.60 valves . They have 64cc Chambers with flat top pistons on a 355 with a 0 deck you will have 10.25.1 C/R . I have a set with the 1.94 / 1.50 valves in real good shape . COOL
