Re: [Chevelle-List] Bad News On Heads... HELP.
Thanks all for your feedback on my issue with the heads- I took all of your advice and had the existing ones re-worked. The guy who did it was very knowledgeable and told me that these heads were in great shape, and it was a good move to rework them- He even admitted as many of you have this week that he has 5 pairs just like them in his garage! Thanks to all who contributed their input on this topic for me this week.. You guys are really helping me meet my goal of having the car see the road this Spring! Best regards, Jim '66 Malibu --- Don [EMAIL PROTECTED] wrote: Unless you want to step up to aftermarket heads, I'd go ahead spend the money on the camel hump heads you've got.

Don Probably worth just sticking the money into the heads to have the work done now that you have them in your pocession unless you wanted to go to vortech heads or are willing to take a step down in performance with a differnt head. The cheapest way to go is probably have them done. mikey - Original Message - From: J.

Re: [Chevelle-List] Bad News On Heads... HELP.
Jim Well I think you should go for the valve guildes...the double humps are a faily good head. If you wanted to update to a newer head its gonna cost you more anyhow. Valve guides changes need a good machine shophard for a do it your self type guy to do. Just my opnion...

snip Probably worth just sticking the money into the heads to have the work done now that you have them in your pocession unless you wanted to go to vortech heads or are willing to take a step down in performance with a differnt head. I'm not sure different heads would be a 'step down' in performance. I would think factory originality would be the driving factor of what heads to use. Don't get me wrong, in their day the 462/492 camel hump heads were the baddest on the block! Now they are overshadowed by all but the most crappy OEM heads. Their combustion chamber is antiquated and it requires a lot of ignition lead to be efficient and make power which in turn contributes to octane sensitivity and you may experience detonation. Now, I'm not saying you can't use them or they won't meet your power goals; because you can and they will...But...Realize that if you have a set of pre-1970 camel humps (and most are) that they do not have ductile iron valve seats in them which means you'll have to replace them in order to run unleaded pump gas. While you're at it you'll probably determine you need to replace the valves as well. Replacing the seats, valves, doing a valvejob, and probably reworking the valveguides so it won't leak will probably set you back around $500-$600. That doesn't include a little bowl work on the ports which I highly suggest doing (though you can do this yourself). What I would do instead would be to purchase a set of World Products S/R Torquer heads. These iron castings were designed as a bolt on improvement/replacement for the old GM heads. Get the set with the 2.02/1.60 valves and get them complete. You can buy them for a little less than $700 per pair! When you get them do a little bowl work to improve the flow a little. Just my .02. I have 2 sets of camel backs in the garage because, even though I replaced them, I can't seem to sell them either! Hoss __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Re: [Chevelle-List] Bad News On Heads... HELP.
One other thing to consider- the SR's have a thicker deck and are probably a more durable casting. I wish they had an updated chamber design though.

I'm also willing to bet he has two sets in his garage cause he wants too much for them. For all the reasons stated... these heads just aren't worth what they once were. I have looked for a set a couple times but most times they are shot or they plum want too much money for them. The SR's are a great head... but to get to the humps level... you are gonna need to work them... which in themselves is gonna cost ya. I had a set of these on a 355 and the were ok... took them off and have them done up and WOW! they were way better! But in the end you still have 800-1000 into them. Vortecs are great and are probably a great fit for this application... but they limit the lift you can run without major work on them, self aligning rockers if you don't have them,and also require a different intake... so how cost efficient they are... well depends what kinda money you have to stick in the humps.

[Chevelle-List] Bad News On Heads... HELP.
Well gang, As recommended by some of the wise men here, I dropped my 327 double-hump heads off for a magnaflux before beginning to install them on my motor. I bought them used and have never used them- The guy called today and said they have no cracks (good news) BUT he said they need new valves and will definitely need guides.. He gave me a price of $80 to install the valve guides. My questions are, I'm already out $50 for the flux- Do I pour the funds into these heads to have them redone? Can I do the valve and guides myself? It wasn't mandatory for me to keep the original heads for this motor or to keep an all original motor by any means, but I don't want to spend unnecessary funds if there's a better decision to be made. Please help- I just bought new springs and retainers for these heads, and now I'm stumped (and actually pretty PO'ed). I just bought the Crane Powermax 260-2 cam kit for this motor, and right now I was planning on using a stock manifold and a 600CFM carb just to get me back up and on the road for this summer.

Re: [Chevelle-List] Bad News On Heads... HELP.
I agree with Mikey If there are original heads worth spending a couple of hundred $$$ on it difinately camel humps. I would have the guides made and install some 202 and 160 stainless valves and hardened seats.
