I think someone in past discussions said that between the bigger valves, thick margins and seat location that the valves are set closer to the deck surface in the Eddys verses factory original.
could be. larger than stock valves should decrease piston to valve clearance a little. the eddy's i'm using have plenty of retainer to seal clearance. piston being .034" in the hole is a little odd.

the true rocker ratio will have a big effect on a hydraulic cam. rockers should be checked for ratio. shelf push rods wouldn't work with the edelbrock heads i'm using and this needs to be checked.
