Guys

I'm trying to nail down 2 x changes.

Could anyone out there with a late red motor with heads off, like a ZR or ZT prefix or a later VB VT prefix please have a look at the inner valley head bolt bosses and see if they are short or long?

Also anyone with a WB or VC-VH 253 or 308 have a look and see if they have 253/308 cast on one side or both sides?
