Haul 'em off for scrap in my opinion. The guy should be paying you to take them out of his garage.

Here's value for your money:

Use this intake manifold with the L31 Vortec heads...

I would also caution you about using a flat tappet cam. Pat McCarthy won't use 'em anymore without the customer signing a release of liability and I won't recommend them either. You can get into a Howard's juice roller for 500 bucks.

An idea I like even better is to find a '96-'00 L31 motor (long block), build it in your spare time at your own pace, then install it over a weekend and sell the motor you take out. They have become popular, but you should be able to find a long block for around 500 bucks. Do the spring upgrade for lift over 0.430". Optional, buy an L31 short block and bolt on the L31 heads I have linked above. They already have the right springs and retainers and are ready to bolt onto your block.

Here are some casting numbers for you....
Block
10243880...350ci/5.7L...95-00...2 or 4 bolt mains
Vortec truck (& other apps), roller cam, one pc rear seal

Heads
10239906 or 12558062...center bolt valve covers and narrow body
"self-aligning" rocker arms. 906 heads are the extra heavy duty and most, but not all, have exhaust valve seat inserts.
