Maybe beg, borrow, steal, or buy a single. Determine off that one what you need for your particular application.

not knowing how much things have been milled, valve install heights etc, you really need to measure with a checking push rod. it'll save you money in the long run.

You should buy a Checker, and be done with it. Especially with a Solid Setup.

3X on the checker. Proper valve train geometry is essential for a good, long lasting engine and valve train. Besides, if you've never done it before, it's a great learning experience. There's always lots of help right here on FBBO.
