Bent pushrod

["Doug & Rett Leithauser" <dleit@worldnet.att.net>]

Arnie,
I recently had my heads apart. I have a 1964 built 260 with non rail type
rocker arms.
On my cylinder heads the hole that the pushrod passes through is NOT round,
but is a machined hole that is very flat on the sides and rounded on the
ends, making an oval. I did not measure the clearance between the pushrod &
the head, but i'd guess it to be near 0.020", I'm pretty sure it's well
under 0.050"
