Hard to follow the post.

What's "jw" and what do you mean by "or what?" it shows up alot.

If you use Magnum heads, you'll need ethier a Magnum intake or have the Mangum heas redrilled to accept an older "LA" intake. The exhaust will bolt up. Port alignment may not be the best since header companys use the old standard design exhaust port pattern.

Also, to use Magnum heads on a "LA" block, you'll need to use AMC lifters and different pushrods. These can be had at the dealer/MoPar Performance.

Does that answer the "Or what?" ? (Ha ha ha, joking.)

On compresion, you'll need to know how far down the piston is in the hole or know the piston height. There are calculators on line that you can use to determin the ratio.
Try KB pistons. I had a link that is currently failing. Grrrrrrr Anybody have a KB link handy?
