'68 302 with 2 different heads...?

So, this is my first engine rebuild so I'm hoping I don't sound stupid. I have removed the heads and today set to tearing them down to go to the machine shop. While removing the valve springs I noticed that my right side head reads "2V" on thew casting. I was expecting this, because the engine is an F series 1968 302ci 2V (Galaxie). When I moved to the left side, though, I was somewhat suprised to see "4V". When I flipped the heads over and looked at the valve ports they are a different shape. This isn't the first strange thing I have encountered taking this car apart, byt the way. The carb is motocraft and it is on a 68...they guy I bought it from says it is the original, but motocraft was called autolite when this car was made. whatever. my question is: Will a car run with 2 different heads on it? Should I just put them back on like that or try to find matching heads? I was disappointed, because I really wanted to keep original parts on this car...

Post the casting numbers. There are 2 & 4 bl heads, plus combustion chamber size diffrences between even the 2 bl heads. You need 2 heads with the same chamber size.
