Quote: Does anyone know if the pushrod clearance is any better on these than the 440Source Heads? We had several hours of grinding to get the pushrods to clear on my 383.
Yep, several had to be filed. That was an unexpected deal. I don,t remember what size pushrods we used without looking on the build sheet . But we stuck with the largest size , was told to not go to the smaller one's. I thought maybe we needed offset rockers but that may not be right.
