rebuilding heads(its my first time,be gentle)

Say fellas, I'm doing my heads myself this time to save money and also
the more of my hot rod I do myself the more satisfaction I get. The
heads are in so-so shape (lot of deposits,gunk). Anyways, how can
I check them acurately to ensure they aren't warped, basic stuff
like that, Thanx

You can check them with a GOOD straight edge but how do YOU check them to see if you have any cracks in the water passages or valve seats? Do you have the machinery to grind the seats and valves? or an oven to bake all the crud off of them? If they are just "so-so" do yourself a favor and take them to a good machine shop for a proper bath, magnaflux and valve job.

There are products that are available to most anyone that can be used to check for cracks. Some use a sort of dye and florescent light. Magnafluxing is best and most machine shops will do that for you pretty cheap. Especialy if you disassemble them and clean them up.

The best thing you can do is go to your local library and find a good book on rebuilding your motor and get yourself informed. There are a lot of things you need to look for.
