Crower Ultra .904 with pushrod oiling ... Looks like these from your description. Link to Summit listing~$850 /set Or is it the version without the "H" in the part number? That listing ~$700, still says pushrod oiling, but not pressurized roller. Do you have a picture of the actual lifter showing where the oil band is located? Many web listing pictures are just "representative" not actual. Manufacturer's Part Number:66233H-16 Product Line:Crower Severe-Duty Roller Lifters Link Bar Type:Vertical Lifter Outside Diameter (in):0.903 in. Lifter Offset:None Quantity:Sold as a set of 16. Notes:With pushrod oiling and Hi Pressure Pin Oiling (HIPPO) option.

I had terrible luck with the Comp 829 lifter in a streeter. I have the Comp 848 AMC spec lifter with hippo oiling for 10 years with 1 rebuild.@ 5 years,,, Went 7/10k miles with maybe 20 passes a year before being rebuilt.
