Hey , are those the summit racing valve covers ? I likem ----how tall are they compaired to a mopar performance big block cover ??
Al's Rapid Transit offers the same valve cover. I don't think that's where I bought mine from. Cause I paid around $104. They're asking $142!!!!!
Only problem was they were bowed in the middle about 0.030" . I used 80 grit sticky back sand paper on a piece of Silstone counter top and worked them back and forth till they were perfectly flat.
