Stay away from the SE 17997-99a pushrods. I had the front intake pushrod back off on me 1500 miles after installation. Luckily there appears to be no internal damage but that $150 trailer ride and the $$$$ for new pushrods was a major pain in the A$$.
I did my research and chose Rivera TaperLites for the replacement. For me I wanted the most number of threads locked into that jam nut and Rivera was 32tpi while SE was only 24tpi.
I read the reports of the tapered Se pushrods breaking the jam nut so I steered away from them quick. I can't remember the tpi of the Andrews but it might have been 28 tpi because I would have chosen them since I am running Andrews cams anyway.

The new SE taper rods are very nice and will find thier way into most of the motors I build from here on out. Again snapping nuts is an install issue, they need to be tight not FARM TIGHT!

Ive installed a few hundred sets of the -99A's and NEVER had one back off, thats an install issue not a problem with the part.

I've spoken with several people that have been working on these things longer than I have and one that has been in business almost as long as I have been alive (50) and all admit they are bewildered.
To the OP, just be aware if you go with a 99a and it comes apart on you, you were warned.

So about a million of these without an issue and you have one that no one can explain. If installed right the op has about as much chance as winning the lottery as having his pushrod come loose LOL.
