Re: Volvo 5.0 FL Head needed
Those are likely a GT40 head but with a marine engineering number. That casting number tells me 1993 Industrial/Marine Engine, and the small amount of info I dug up tells me its pretty much a standard GT40 head. If you poke around on the various Mustang boards ,you can probably turn up a set. There is a difference between the GT40 and GT40P head though, so be sure of what you're getting. Also, be sure that its a GT40 iron, not one of the Ford Racing aluminum heads with similar names.
BTW, the 1993 just means thats when it was designed. It has nothing to do with when it was actually made.
