i am putting a 454 in to my 66 chevelle and it needs valve covers i was lookign through a few magazines and some valve covers were short and some were tall which ones should i get

well due to aero-dynamics, id go with the short ones, less air resistance http://www.chevelles.com/forum/biggrin.gif.

Short's are fine for standard rockers, Tall for roller rockers. I believe some members here double gasket short covers to work with roller rockers also.
