Gotta build ANOTHER engine.

To answer your question.........yes you should have degreed your cam, you also should have checked piston to valve clearance...........water under the bridge/spilled milk now at this point. You are not the first and you won't be the last........Degreeing the cam is not that hard, it's time consuming, but it is not THAT hard......beyond the degree wheel, you'll need a dial indicator, magnetic base, positive stop, something to bridge over a cylinder with a piston installed, feeler gauges, or a set of calipers for measuring deck height, piece of coat hanger bent up to be a pointer.

I type too poorly to tell you how it done, there has got to be lots of tutorials on how to degree a cam here on the web that will help you along.........in this matter, time and patients are your friends

Good luck!
