Get em done right they are a good set of heads.....port match, unshroud the exhaust valve wall and match all valve heights......( change out seats and valves that are sunk in heads). Mine are on a 406 smblk.

Re: Got Me some Camel Humps!!
I think I will go with the 268H cam from comp. will it work fine with stock springs on my camel humps?? Assuming they are stock springs.

They should work, but it is always recommended to check for coil bind and retainer to valve stem/seal clearence, when upgrading a cam.

Re: Got Me some Camel Humps!!
I agree with Captain... always double check. As for cam another thought would be the 279 thumper series from comp cams. It is designed to give ya a racier idle and a decent performance boost with out all the hassle of a large cam. Not downing the 268H cam, as it is a fine little cam, but it is 30 year old tech. The newer designed cam profiles can accomplish a lot more with alot less motor. Just a thought.

What kind of heads are these on my 283? http://i1106.photobucket.com/albums/...psyjsct97i.jpg http://i1106.photobucket.com/albums/...psaxm6myqj.jpg |
Re: Got Me some Camel Humps!!
The best thing to do is remove a valve cover and get the casting number. All I can tell you from the pics is that they are a '68 and newer head.

Re: Got Me some Camel Humps!!
If it were me when ever doing a cam swap . I would always buy the cams valve Springs to match said cam as well. It is a peace of mind that is money well invested in your build ... so if you can buy a full cam and lifter set with matching valve Springs. . Also something I have not seen anyone ask you or mention to you is . Do you have power brakes ? Because if you do and you get a cam with a big lope sound that means way less vacuum which means poor brakes if they are power assist. For that you will also want to buy a vacuum can from summit so remember more lope / thump means less ability to stop at lights . Without running a vacuum can .. Happy Truckin

Actually,it appears after looking at both pictures that you have 2 different heads. |
Re: Got Me some Camel Humps!!
FWIW,the humps were great heads back in the day & if you're trying be period correct,that's 1 thing,but,if you are looking for performance & efficiency,that's a whole different thing.
A set of L31 Vortec heads,or,any of the similar fastburn heads will be an instant 30 HP over any of the humps.You can make more power with less cam & have much better resistance against detonation. Unless they have had hardened seats installed,a performance type cam & springs can beat the soft seats out of the head in no time flat. By the time you have seats installed,install screw in studs & a valve job,you will have a lot of money tied up in a set 50 something year old heads that will be less powerful & efficient. |
Re: Got Me some Camel Humps!!
I'm trying to find the other post - I think by you - where you say something about a good newer head that works good on a 283.
