i'm in the process of having a 496 built for my car I want it to appear factory under the hood but we are using roller rockers I noticed year one sells a replica valve cover that's 1/2 inch taller but theyre 70 bucks I cant see the quality being that great being that cheap has anyone used these?
Without reopening the whole "Are Aluminum Roller Rocker Arms Worthwhile for a Street Engine" discussion... What is your intended use for this engine?
I used Roller Tip Rockers on my 454 HO/ZZ454 when I swapped in a mild ZZ502 Camshaft. The 454 is not a killer, but it is a well rounded engine that is fun to drive.
I topped the heads with factory-style Valve Covers. No clearance issues whatsoever.
This begs the questions: Do you
need a Camshaft that is so aggressive that it requires Roller Rocker Arms? Is your engine builder over engineering your mill? And why?
I see an awful lot of street-used engines that are (super cool, but
) way, way overbuilt for driving to and from a car show... My buddy has an A12 '69 Dodge Stupid Bee 440 Six Pack. He spent over 15 grand on an engine which produces gobs of horsepower. The Stupid Bee has never seen a Drag Strip and (despite my urging
) never will. My buddy only drives the Stupid Bee to and from car shows and therefore it might as well have a slant 6 in it.
Just sayin' ... perhaps a less agressive engine might meet your needs better.
