The heads will bolt on, absolutely. All 350 type heads are pretty much the same, as far as bolting to the block. The one odd-ball of the group is the 400 engine/heads. They are different, but the 400 heads can be used on a 350 block by drilling some holes for the steam pockets.

The fast burn heads are an improvement over just about any "stock" 350 head.
A stroker engine will almost always need a better intake trac to work properly, this includes the intake, and the heads. Adams' Apple2007-02-24 22:25:15

thanks for the reply, i also found out that i can't use my hooker side pipes with the gm aluminum fast burn heads! that stinks! it might be worth giving up the sidepipes though for more torque!

You can use your sidepipes with the GM Fastburn Heads.  That's what I'm running.

hello joanne
 
the zz 383 puts out 450hp@5600rpm
                                
and the torque is     488@4400rpm
 
it is from gilbert chevrolet, however i live in alberta canada and they will not ship it to me! my local engine shop will match these engine numbers.
anyway i thought that wasn't to shabby for those style of head.
