...I went with the CompCams Pushrod at 3/8"
There was plenty of Clearance with the Iron 4V Heads, But! I had to Grind/Polish the 'Bottom' of the 'U' Shaped Yoke, on the GuidePlates as the Rods Rubbed there. These were 3/8" GuidePlates, the 'Fork' was just a little Shallow, an Easy Fix!(I Think the Plates were Manley Or CompCams). The Rods were Standard Length, used with Roller Rockers. I Believe 5/16" pushrods ARE too Weak!! I also believe in 'Massive OverKill'!...
