320HP Magnum Crate w/ X-heads

Does ATK supply some sort of spec/build sheets for each build? That would be sort of an easy button to find out what has been machined and what not. I think stock Mag heads are in the 65 ish cc area for chamber. Not hard to get the X head to that spec. Just losing a little quench. Omg!!! I just said you might lose a little quench!!! There's the caveat!!!!! I'm being sarcastic. Have never measured actual static on a Mag. Were supposed to be 9 ish to 1? Someone can chime in on actual MEASURED specs if they have them. Point being, you seem to be willing to spend money and go through a lot of work to buy a new engine and tear it apart right away.

The initial thing that made me consider this Magnum is that it was deeply discounted from Summit. We already have the x-heads and LD6B so the new Magnum heads can be sold to cover the cost of pistons or a cam.
Hopefully the Magnum pistons aren't way down in the hole and we can make up some compression by slightly milling the head and using a thin gasket.
Also, instead of having to find a new block and rebuying all the engine parts that I had originally given my Dad for the early LA 360 I get those back. The way I see it is I am possibly saving money in the long run. I was planning on building it but not anytime soon. Pops was wanting to repower his Cuda this year.
