Okay well.. How about pushrods? I'd like to have everything ordered and at hand before I tear it down. Trying to minimize down time as much as possible, anyone know what size pushrods I'll need with the 503 and 1.6's? Not sure if changing out the rockers changes pushrod length... Or if there's a set length that "should" be right with that set up

You should technically measure for your Pushrods with a pr measure tool but with your setup I was fine with stock length 7.2"

Okay cool, I know they should be measured, but I really didn't want to have it all appart and wait 3 days for new pushrods to ship before I could get it all buttoned back up, thanks guys

Now, on a separate note and probably should be a separate thread...

What's all included in switching over to a 373 on a posi rear end?
