Hello to everyone , this is my first post . I have a 1977 460 and a
chance to get a set of 429 DOVE heads . Does anyone know if they
will fit ? I appreciate any help .


Thanks ,

Bill

yes they will just did a 512 with them

Grab 'em! With a cam change, and D0VE's. a 460 will really come alive.

Might have a set of them Pat, I'll take a look on Monday......

Thanks for the info , I just got a new XE 274H-10 Comp cam with double springs . I had roller rockers on the 460 heads but they only had a 5/16ths
screw in stud and they won't handle that much lift . I'm pretty sure I'll need
new rocker arms I just need to find out which ones . Any info on that would be appreciated too .

Thanks ,

Bill

Bill,

They are a bolt-on replacement, and will accept the 1977 intake manifold, exhaust manifolds, etc. Compression ratio ofyour 1977 460 will jump from 7.9:1 to 9.1:1.

However, the valve trains between the D3VE (<---1977) heads and the D0VE heads are different, so you will need the proper valve train to install the D0VE heads. Aftermarket valve train componentry is best.

That cam is pushing it on the pedestal-style valve train, but can be made to work if properly set up. I have a similar cam beneath D3VE heads and OEM valve trian, and the engine runs fine.

But the rocker arms that you need tor the D0VE heads will be aftermarket 7/16" stud applicable, ideally. This will require 7/16" roller rocker studs, pushrod guide-plates, hardened pushrods, etc. Trimming down the valve guides so as to increase guide-to-retainer clearance is a good idea while the heads are being prepped, but not necessarily mandatory with that particular cam. Crane Gold Series or Ford Racing rockers would be your best bet in rocker arms, and there are others such as Scorpions. STAY AWAY for the cheapo Ebay rocker arms! Lastly, you will need to establish proper rocker arm geometery with your new valve train, and will likely need longer-than-stock pushrods...and the exhaust pushrods will likely need to be longer than the intake pushrods due to the valve train layout on these engines.

Thanks for all of that information . I already had 9: 1 flat top pistons .
I'm trying to digest all the info about the push rods . The geometery
part is pretty much greek to me . Looks like I have some studying to do .
I just got the heads home and the first thing is a good cleaning .

Thanks

Bill
