The Sharps may be a little "wide" for your valve covers, whereas Cranes will work under stock covers. I use the inexpensive Crane's, adn I think they are fine unless you're running race type spring pressures.
i just bought a set of scorpion aluminum rockers. very reasonable and very nice pieces. i havnt run them yet but i did alot of research on them before i made my purchase. we have alot of guys running them around here with no problems as of yet. go to competition products web site for info. they have them for $199.
