You could also just compression test the cylinders. This way you don't have to take the head off to know whether there is engine damage.

You should see that valves for the bad cylinders are bent and can't properly seat. There may also be damage to the tops of the pistons.

If only the valves are damaged, consider just buying a replacement head.

i found a whole new used head in minnesota that all it needs is to be resurfaced............only 75$ for it...... when i go to put this back together i make sure the head is at TDC and i can put the crank at TDC with the head being off right?
