cylinder head Identification
 

Trying to figure out which heads are on my 5.0. They have SVO engraved on the front of them and they are aluminum. Any Ideas are they some sort of ford racing head? Any info would be appreciated, thanks.

If they have SVO in them then yeah they are some kind of Ford Racing head. Maybe the older model heads they used to sell under the nu315# i think is what it was called. I will see if google comes up with some info for ya.

cool, thanks man. I might have to pull the valve covers off. I think if they are ford racing they should say like x303 or something like that.

Yeah get the numbers and it will be a lot simpler to figure out what heads they are.
