Where can I find these tools?

I have a Helm's manual and it gives a model code for the in car valve spring compressor, but I don't know where to find it. Can someone help? Also, are there any other good in car valve spring compressors that would work on an H23a, or is there somewhere I could rent or borrow one from, like autozone? Also, I'm gonna need an air compressor with bolt attachment to put into the top of the cylinders to pressurize them and keep the valves from falling in, but I don't have one. Where could I borrow/rent one of these? Any help is appreciated, especially if you have valvetrain experience. Sorry to all of you who gave me advice to remove the head for this work, I just don't have extra money for a new head gasket. Plus, when I take it off, I might as well get some work done on it, P&P, so I gotta wait till I get more cash for that project.

go to a automotive type tool place they should have it

What do you mean by that. Somewhere like autozone?
