Ron,
I would definitely be interested in a set (maybe two sets) of roller rocker arms and shafts for a 261. I am not looking for much, if any, increase in lift ratio if the pushrod holes would need to be enlarged. I ruined a head once enlarging the holes for a set of B&B rocker arms back in 1957. If the shaft could be offset as suggested by panic in step 7 I would be interested, depending on how much lift could be put in the cam lobes. I would also be interested in a set of roller rocker arms for my 12-port head on my other 261. I understand that the existing rocker arms used by Wayne Horning et al. are from a 1941 Buick straight 8. I live in St. Louis, so a trip to KCMO would be fairly easy for me.
