hi again, i got a sweet looking pair of new trick flow valve covers for my 5.0 - part # TFS-51411801. i have 1.7 roller rockers so clearance is an issue. i did a little research before i bought them and trick flow's site stated they would clear roller rockers. i ordered the valve covers and the order confirmation listed them as "standard height" - but with the same part number as the ones i looked at on the trick flow website. so this has me wondering. i'm sure that the standard height will still clear the roller rockers and that is just their way of seperating them from the really tall ones that are used on full tilt race heads. but... just to be safe - has anyone bought these valve covers and how did they fit?? i know i will have to drill my own breather and oil fill holes but that's cool since a dremel tool with the right fittings will solve damn near anything.
