I have the LO3 in my 91 bird and I always see tons of parts (et. valve covers) and stuff for everything except centerbolt heads. I really would like to know what that means, lol. Also, what would be the best heads to put on my LO3 if I plan on building it up. Thanks.

 

Just mean it uses centerbolt valve covers instead of the typical perimeter valve covers.

 

Thanks. Could anyone explain in just a little more detail? I kinda figured that out from the name, lol.

 

That is basically it. There perimeter has two bolts on each side where the valve cover meets the head where as centerbolt has a row of four bolts raised up on top of the valve cover in a row. Sorry no pics.

If I read your post correctly, you are looking for some good centerbolt heads?

If so, that's easy, get the Vortecs.
