Header Size Recommendation

Back from the dead...

I just bought these:
Dodge 318 360 5.2 5.9 NEW Stainless Steel Racing Headers Magnum 5.2L 5.9L Dakota | eBay (Link reads wrong, but goes to Hooker 5204's that I bought.)
I've had searches saved on CL and eBay; not much has popped up, till now. I almost went with TTI's (1 5/8 to 1 7/8 step), but that's like $800 w/ shipping!

Yellow Rose, if you happen to see this, I appreciate your thoughts on 1 7/8, but here I am.

Now, I just need rings, bearings and a starter to install the engine and trans.

Yeah, things take me a while sometimes, lol. But I've been working on the body while I save money. Also working on my body, lol, I've been down for 5 months because of torn rotator cuff.
