Crabman and Dunnuck, I know each engine could be different, but in general, what is the pushrod clearance like with these heads and 3/8" pushrods and 1.5 rockers? Have you had to grind for clearance or not had to grind for clearance in most cases? Thanks!



I did not hear anything about the clearance. If there is before, there is not afterwards.




Steve I am doing one later this week on a 440 with 3/8ths pushrods and a .575 solid roller with Harland Sharp 1.5 ratio rocker arms I will let you know how it works out
