Newbie question, year model Options

[ventilator01]

I just bought a porsche 914 2.0, lost title and I have a bill of sale. I bought it as a 1974 but wanted to make sure thats what I have. This numbers is along the windsheild on the drivers side 4742905917 There is a plate under the hood on the passenger side headlight case the only number on it that i can make out is 474. Another tag in drivers side door jam is 4239550. I bought this car as is, and it needs a head ($1500.00 is what I paid for car), was thinking it was just gonna need a head gasket.... but it needs the head and the jug under head. I know I prob got screwed, but really wanted the car. This is my first porshe, will post some pics after I get the head and get it home. Thanks for any info offered. I live in Georgia about 70 miles south of Atlanta
Thx

Since the heads are aluminum, they can be repaired...might be costly, but they can be repaired.

Which head....driver or passenger? The passenger side will have the threads for the CHT on your fuel injection.

When you say you need the jug & head, you are saying it dropped a valve, destroyed the piston, cylinder and head....correct?

Welcome to the insanity.......
