At least it seems this way comparing 1.52 to 1.55+

I've got good piston to valve clearance (now that I'm on my second cam), my intake valve relief has a little extra to accomodate the Edelbrock valve, so
that all seems good to go.

Pretty small bump in the road really, but something tells me I'm not the first to encounter this.



so Zippy what was your resolution for this? Im have clearance issues too with a 3/8 pushrod and a victor head. Im thinking some .110 wall 5/16 will work. Using a small solid roller with 829b oiler rollers.
