Yes on the 48 degree. I checked double checked with a45 degree cam and then tried a 48 degree cam. My machine shop Ted at Opel Engineering mentioned that KB did the 48 degree to a lot of Wedge Blocks. The lifter bores are bushed.

With the 45 degree cam the no. 1 intake lobe was full lift and 180 degrees after the no.6 intake lobe was at full lift around 8 degrees early/late can't remember which one.

Tried a friends hemi 48 degree cam (used the exhaust lift instead of intake on no.6)and the no.1 intake lobe was at full lift and 180 degrees after the no.6 intake (hemi exhaust) was at full lobe lift at exactly 180 degrees later.

Any other ways to check? The whole short block is assembled and really don't want to disassmble again if not needed. I think the above test helped determine the 48 degree angle.
