I got a question. See if u can help..

If a motor starts, has 150psi on 3 cylinders and 0psi on 1 but gets compression at high rpm's and it sounds like it has a exhaust leak or somethin, is that a valve?

most likely, did you pull your valve cover off yet?

do a leakdown test on it, you'll be 100% sure by doing that, without taking the motor apart
