just bought a super dupra, noob to the car

[bleSId]

ok so here's its story.

i bought the car for 200 bucks, according to the lady i bought it from the timing belt broke and when it did that it broke something in the no. 3 cylinder. i have no idea wat broke im pretty sure it wasnt the piston could've been a valve but again im not sure. i just did a compression check and the rings arent fried so that good.

i know im gonna have to take the head off but other than that, thats about all i know.

so my question is: with the information i just gave you guys how complicated is this gonna be?
