Which pistons do I buy?

Couple of things to add...

The heads that Steve has are 94 3100 heads ported by Ben. So they are the smaller intake valve and stamped rockers. Ben might be able to remember how much porting he actually did.

If you need an adjustable pushrod, let me know. I have the one that actually works (Crower is the only one that makes one small enough), and I have no use for it at the moment. So I can mail it to you so you can use it to figure out what you need, then just send it back whenever you get done.

That would be cool Brad!,go ahead and send it.
I remember from the begining you said they were 94 3100's
What valvesprings/retainers should I use? Keep the stock rockers? or aftermarket.
