318 rebuild, whats the best combo?

i thought magnum heads didnt work with the older engines... and what size heads? 318 heads, or bigger?
tappet angle was it? bolt pattern maybe, i dont really remember, but if you tell me how to do it, ill give it my damnedest :). sounds gooooood to me!

whats the stock ratio for my car (gears)? anybody know?

1 5/8 headers right?
im gonna see about pipes soon, 2.5" w/ X pipe and like, 40 series delta flows... dual, thats what i planning on.
my dad's friend has a muffler shop he's about to dump off, but i can get a discount on it if i act fast.
