if i were to buy a pair of stock heads off of a junker 5.3, what would i need to port n' polish them? any special procedure to do it, or could i just grind away?

Don't blindly try to port your own heads without a whole lot of research, reading books, videos and such. Porting heads properly is an art. Its worth the money to pay a knowledgable person to do them right the first time.

Absolutely nothing but how do you measure your gains?

How much experience do you have porting or machining?

You will net most flow improvements from valve unshrouding and if you have no idea how to do it you will end up hurt your flow numbers by either taking to much off not in the right place. Have you looked down an intake port on a LS style head. There is some to be done but not as much as one would think. I only notice one major spot that need to have a decent bit of material removed other than the opening for port matching.
I mean if you just want to play go for it but if you are playing I would run them on your truck, you will end up losing power if your not sure what you are doing.
Step 1. crus at it.
Step 2. get a hammer.
Step 3. torch it.
I ported the heads on my ls1 GTO by simply spraying an outline over the header gasket as a template. Ran great till the day I sold it 1 year later.

i would say thats just gasket matching. there is a lot more involved in a full port job. like others have said unless you have experience stay with gasket matching or tinkering with old junk heads. i guess you gotta learn some how right? gary
