Alabama Cylinder heads, question

xjtrailrider said:

I was just looking through the site and they only list one head casting for 91-01 and its the 0331 casting.

Is this just some "new old stock" or is this a completely new and up to date casting that won't crack like the original 0331?

Anybody else have one? How has it held up?

Edit: This could have been in OEM instead so Mods feel free to move it if needed!

If you go to Alabama's eBay store, they list the castings as 7120, 0630, or 0331. And they say that these are all brand new. I'd call them just to make sure.

And FWIW, Alabama and Patriot are affiliated.

Looking at Alabama's website, it show one head, Model # CHR640N, to replace OEM heads 063, 7120 and 0331.

I thought the 0331 head had much different exhaust ports than the 063 and 7120 heads.
Wonder how they do that.

I guess that the small exhaust ports of the 0331 would still work with the older exhaust manifolds. The bottom of the ports is just raised. I know I've seen some other shop on the internet that lists different heads for pre 1999, but I haven't been able to find it lately. I'd look for a 0630/7120 on craigslist for $50 and build my coil rail adapter if it's for 99+.

This may be a dumb question, (mostly because I'm to tired to go out to the driveway and compare the different model years) but can the other castings be drilled and tapped to accept the COP's so I would not have to make brackets.

We have a 90, 94, (2)96's and a 00. The 00 has the 0331 head and its sitting at 110k so it is about due to crack. I want to have a head ready when it goes.
