I bought a set of tall polished aluminum covers for my 454 that would clear roller rockers. They clear the manifolds and valve train just fine, BUT, the linkages on the stbd manifold interfere. I suppose if I added riser extensions, then all would be good, but I have stock rocker covers on now. Polished covers still in box collecting dust.We have a 88 Baja Force with a stock crate 502 motor; Gen VI to be exact with the stock blue Chevy roller rocker arm, what valve covers will work with my stock exhaust elbows? Anyone have any input?
