Mate, I wouldn't even worry with a compression test. Do a leak down test if you want to know for sure.

If you really worried. Take the block out and send her to machine shop ~$500 (depending on how far you wanna go whats really broken) add ~1k if you cannot remove and disassemble yourself.

When you get the motor back your vtec will go BWAHHHHHHHHH!

Best time to add cams or b20 if you ask me. I'd spend that extra 2k on a better valve train and rev to 9k on sweet cams. Add that extra offt to your BWAHHHHHHH!
