Get a set of doctile adjustable rockers or leave well enough alone. for a street engine you will likely notice very little difference in the ratio difference in the OEM and the more accurate adjustables. Here is a excerpt from a Mopar mag. It is referring to small block but the same holds true for bb engines.

It's kind of surprising you don't have a flat/ damaged cam lobe already from running those used lifters, and you'll be taking another chance when installing that new set. A lot of people on this board aren't so lucky even with all new parts. I hope this all works out for you and you've Dodged a bullet. 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

A lot of people on this board aren't so lucky even with all new parts. I hope this all works out for you and you've Dodged a bullet. Over ther years Ihave seen people that put the lifters in a box and reused them when reassembling. Making sure that the lifters and cam are clean and well lubricated and they end result was no problem. Granted it isn't a good idea but if you have run it for even a relatively short time with no problem I would not worry about it and run it. Save your money for later up grades. The damage would have been virtually immediate.

These lifters have less than 15 miles on them plus 10-15 min idle time after installing them.

All pieces in related assy's are different (clearances/yield points etc) & will act different under fire. For a start I would check V/P clearance on ANY cyl. Something stacked em up solid (K.I.S.S. = vp collision) live every 24 hour block of time like it's your last day on earth

Something stacked em up solid (K.I.S.S. = vp collision) yes this. and over 6000-6500 rpm or so (plus or minus) hydraulic lifters will pump up solid and cause problems. i dont think you were running over 6k, so it's more likely that your pushrods could be too long. if you like running high rpms you should have solids (this requires adjustable rockers). do you have a good local machine shop? you should go explain the issues they would probably show you how to measure things and get it right. you might need a cut-to-fit pushrod kit and the guys at the machine shop can help you get your baby right my recommendation: get a solid cam / solid lifers / adjustable rockers / cut-to-fit pushrods / pushrod measuring tool / have a machine shop help or teach you all the details / know how to adjust them you will never have these problems again Last edited by 74yellowduster; 02/16/13 11:36 AM.
