Bought a truck years ago with a Magnum Stroker and bought a set of Magnum Valve Covers a year or two ago. I'm wanting to put these on the truck but, I'm wondering if I will need spacers to run the valve covers? The reason for my question is the truck has a different valvetrain. It has aluminum heads with 1.7 Crower Rockers Arms and it has a Hughes Custom Grind Camshaft. Cam is 228/336 @.050, .560/.565 on 108 degree LSA but, I'm assuming those numbers were based upon a 1.6 rocker arm ratio. Anyway, I'm hoping I won't need spacers but, it's some wide style LA Valve Cover on there now. Attached is a picture of the valve covers currently on the engine and another picture attached of the valve covers I'm hoping to use. Thank you in advance.
