In my short experience and from what I've heard from my builder the 441s work great but go through exhaust seats pretty quickly.

For the money

6" Ohio Crankshaft Bushed Rods (I Beam)-$189
Scat 9000 Crankshaft-$169
Keith Black Hyperutectics-$249
Block-$150 (If you have one rule this out)
Bore/Hone/Balance-$250 (Depending on machine shop)
Re-Ring Kit with Good Rings/Bearings/Gaskets-$149
Heads- 1.94/1.6 w/ Screw in studs and .600 lift springs from Race shop-$400
(Or you can buy new valves and have someone locally do your heads cheaper if you have cores, but not much cheaper)
Pushrods-$24.96
Camshaft with Lifters- $230 for a Custom Cut Cam, this WILL make a difference
Oil Pan-$59
Oil pump w/pickup-$35
Valve Covers-$20 Bux
Intake-$25 at local s****yard
Timing Chain-$39.99
Timing Cover-$10

This will make a real screamer for about $2,000 that'll last you a LONG time if not bought. The biggest thing I will stress is to balance it and choose the right camshaft. You can put a stock 5.7 re built rod with arp bolts in for a hundred less, and save 50 on a GM Crank, but I really think a 6" Rod motor will be a better motor overall.
