Any drawback to having a hydro head on a JH?

[jtoomasson at yahoo.com (Jeff Toomasson)]

Actually, Rick - that is typical for a solid lifter head (I have two in my
garage  :).

The H for the hydraulic designation is located directly in the center of the
front of the head on the same level as the part number. The part number for
the hydro head is  026 103 373 F...
