Is milling the guides all that needs to be done to the heads to run something like an xpz?
I know I need like 130# springs and retainers and a double roller. (can the stock pushrods handle that?)

Yes, all you need to do is mill the guides. A port and polish is highly recommended, but sounds like you are getting that done.
The xpz requires different pushrod lengths. Stock is fine strenth-wise, but they are not the correct lenghts.

What about the s3? same lengths?
Its starting to sound like I should wait on the cam until I have a good chunk of cash to throw at it, and just go e85 for now.

When you buy the xpz new or used it usually comes with the rods
my s3 cam used 1 length

Dude. I looked at s1x cam with a more lift using 1.8 or 1.9 rockers but same duration. Then I looked at the xpz vs s3. I considered a custom grind but I could what I found was if it could have been done it would have already. Soo many numbers being thrown around.
Searched for days on actual s3 and xpz 1/4 miles and dyno charts.

I think Im going to e85 first, if im going to bother with a cam I might as well go for the throat.
I can e85 the thing for 500, a "Proper" cam install with a big boy is going to cost me closer to a thousand it looks like.
cam, 330, lifters 100(my LS7 have metal in them) Rings 120, retainers 40, double roller and install parts 150, gaskets 100, misc head work ~50-200, tuner 260 depending what I get done.
e85, Injectors 250, tuner 260
( I could just throw 42# and go too)
I appreciate all the info!

Budgets. Sure as hell didn't buy mine in one shot. Buy used , shop around, collect and be patient...
look for someone demodding and grab some 42s and see if you like the corn method
