Tick Tick goes the magnum.

Hey guys, so i had a couple questions, i upgraded my magnum camshaft, along with hughes springs etc, i kind of knew the stock push rods would work but tried to get an idea and yup the stock rods at 6.900 were too short the rockers were all loose.

So bought a push rod checker used a sharpie to mark the top of the valve honestly that method didnt really show me a clear mark (maybe i needed a paint marker) but it looked like the motor was wanted a 6.945 pushrods so i ordered some 6.950 Hollow Pushrods.

After starting the engine i can hear it tick!!!! Not extremely loud but mild, i can hear it thru the carb, i also can hear like cylinder pressure if that makes sense while the engine is running feels like its got a vacuum leak or something.

Could the push rods be too long?? or Too Short??
