How much material is around the pushrod holes on a Trick Flow 240 head? The holes are 1/2" wide and should work fine with 3/8" pushrods so when going to 7/16" pushrods I would need to open the hole to 9/16" to get the same clearance (1/8" total or 1/16" each side).
Or did you make the hole even larger?
The holes are very close to the intake ports and I don't know how much material can be safely removed...
Thanks
