chip, 
thanks for the info about the lifter bores. Can you or Ted confirm if the non-verticality is a factory machining error or deliberate. I have never done this on TR blocks, so I've never had cause to look that closely.  I had located some very light 22mm Toyota ones (o.866"). What model Ford uses a nice light solid lifter of 0.875"???

can you share with us some data on the sorts of cams you are sucessfully running with these bigger lifters.

thanks, Terry .
