I thought some had a 14 bolt pattern for the valve covers and others were 9. Not sure on the exact numbers but pretty sure there are 2 differant types. One pattern for Romeo heads and one for Windsor heads.

Just always on the lookout for spare parts; never know when I might need them.BigFan: The Romeo heads; is it just a different valve cover? Like different bolt pattern or something.
Also; is there any difference other than crank and pistons from a regular 5.4 to a L 5.4?
