Diffeence Between Integral Head & Non Intergal
So what is the difference between the two? Is one better then the other? What years where each made? I was thinking of looking for a streight 6 and want to be informed. Thanks Gary

Re: Diffeence Between Integral Head & Non Intergal
An integral head has the intake manifold built into the head itself. It is all the same casting. The earlier "non" integral head has the intake manifold as a seperate casting that bolts-on just like the exhaust manifold.
As a general rule, most guys prefer the non integral.

Re: Diffeence Between Integral Head & Non Intergal
IMO I would look for the older model inline six. The intergral head come out in the late 70's I think. I know my 81 has one. The intake manifold is cast with the head so there's no changing them for any performance parts. Now I don't know if the head off a older motor will fit the new blocks as I haven't researched it.

Re: Diffeence Between Integral Head & Non Intergal
The integral heads started in '75, IIRC.
You can use either one, they interchange.

Re: Diffeence Between Integral Head & Non Intergal
The intregal head came out in 75 like Longhorn say's although they didn't use it on Camero's & 292's. They were real bad about cracking the heads & ex. manifolds & broken bolt's in the ex. manifold. The head was ungodly heavy & burdened down with weird emission control gadget's. It's best to stay away from them.

Re: Diffeence Between Integral Head & Non Intergal
Don't let the above discourage you if you have the chance to buy an otherwise good engine with an integral head. As already mentioned, the earlier head is a straight across swap on any of the 63-up inline sixes.
