Default ZZ4 valve cover question.

If I were to take a new ZZ4 and change the rocker arms requiring a taller valve cover(center bolt), what covers would you guys recommend????

Thanks in advance. :)

I've read in Chevy High Performance that one of the best buys for a ZZ4 is the GM Performance Roller 1.6 rockers. They will fit under stock center-bolt covers without mods. These are self guiding rockers which is a necessity with ZZ4 heads. If you use anyone else's roller rockers (non-self aligning) then you'll have to run guide plates.

I don't know of any tall centerbolt vavle covers, or a need for them.
You could, at big expense, use the center bolt to standard valve cover conversion kits. But at $160 just for the kit, I would have to ask "Why?"

Crane Golds will work under the stock covers.
