I'm trying to find either a Trickflow valve spring, p/n 51400413, or a readily available equivalent. It seems the Trickflow number may be obsolete. The corresponding retainer seems available, a 51400423, but not the spring.
My previously suspected rod knock now appears to be a broken spring and bent pushrod. I'm trying to source these numbers, which were in the paperwork from the previous owner/machine shop. The Trickflow spring 51400413 and Pioneer valve lock PF613HD are documented. The retainer p/n 51400423 I surmised from Trickflow documents found on the web that matched it to the fore-mentioned spring.
The cam is a Bullet 230 dur @ .050, lobe lift .3027 I and E, gross lift .524 I and E.
Any other p/n's would be greatly appreciated. I'm hoping to source these locally so I can quickly confirm this was my problem, and not something requiring rebuilding the short block.

From here, I can't really comment of the the other products, but if you run it hard, perhaps you might want to consider different valve locks? ;)

I found the numbers
The valve locks and retainer actually did their job quite well.
