Welcome, body looks excellent,do you know the extent of the damage? (how much did you "pay" for it if you do not mind?). A new engine would be the best route, but if everything looks good on the lower end, you may just need to buy a head off eBay. The timing on the car is tricky, you will need to be very careful so you do not lose the new engine

You will find a lot of useful information here though, just not from me
