Identifying my inline 6
Ok, I know you all will think this is lame but I need to find out what 6 I have in my 58. Think it's been swapped since the guy said so. Not sure where the numbers are and then where to go to decipher it. I have searched the net and haven't found anything on it. Any help would be great!

Pics?
Look for numbers above the starter.
Intake and exhaust are on what side?
Does the intake bolt to the head or is it cast as one?
There are some noticable diffs between the older 223 and newer 240/300.
Here are some pics of a built 300, modified, but you can see the valve cover and how it is shaped.

The first two digits of the casting number say that it was first meant for production in 1981. That is definitely either a 240 or 300. The only way to tell for sure which is to measure the stroke.

It's a 300, the 240 stopped production in 74 or 75, and generally people replace the 240 with the 300. It'd be really odd to find a 240 crank, rods, and pistons in an 80's 300 block.
If you want to check the stroke, use a dowel about a foot long down a spark plug hole. Mark it at the piston's highest point, and at it's lowest point. If it's about 4" difference between the marks, it's a 300. If it's a little over 3", then it's 240 innards in there.

I was hoping to buy a 240 head for my 300. Does this mean that I have to have the head off in order to distinguish the differences?
My goal was to increase the compression by using the 240 head. Are the valves the same size in each of those heads?
