They started that when hydraulic lifters came in because the rocker was in constant contact and they want to oil the area better. I put one like that on my 216 and the oil still goes all over as required. I also thought that if I didn't like it I could drill the oil holes through and install it upside down. I don't think it would have any affect on the top. | | |
