I need to replace the heads on my OMC (Ford) 5.0L efi motor.
I was looking at the price for new heads from OMC and almost died.
(1300 @)
Is there any reason I can't use heads from a car with the same motor
and just change the freeze out plugs?

I thinkt hey're the same. except the marine probably has steel valves.

I'd try it.

PLUS ! You have to rememebr,t hat the marine store is giong to charge
full list price on those heads.

you could get DIY though an auto parts store or machine shop for
considerably less.. Call NAPA etc, and price some exchange heads.

Thanks. That's kind of what I thought.
Just ordered a set of heads complete for 600 total and they are going
to put the brass plugs in for free.
2600.
600.
-------
2000 saved. Were is that radar dept?

Thanks again

Huh? What material would the auto engine's valves be made of??

==================================
You don't mention the model year. I have a 1988 OMC, 5.0 and its built
on a 305 Chevy engine. You may want to check this out.
It could drive a guy up a wall to try to put a Ford head on a Chevy
block......

Happy boating, Norm

OMC DID use a chevy engine, but he already mentioned it's a Ford.....

I just re-read the original post and I didn't notice that it was "efi",
so this is a later engine than the 1988 version.
