Sheesh, now you are getting picky..... ;D.   I'll weight a set of steel stock retainers when I get home today to compare.

Whut's a Rimac? Valve spring tester?
Yes sir.
  And they are now out of business.  WE have two of them.
Supply was extremely sketchy for new units the last 8 years. Take one apart.....something out of Bedrock in terms of mechanical sophistication. Some very nice digital units out there.....just very expensive.

Still waiting to hear what the weight of the stock retainers are. ;)

OK, you got me.  I found that I actually did not have any factory stock steel retainers handy like I thought.  So out of pure guilt, and curiosity, I grabbed one of my crusty parts motor heads and pulled the 4 intake springs retainers and keepers.

So, we have:

Aluminum RC retainers.          60.9 grams for 8
Titanium (? brand) retainers   96.8 grams for 8
Factory steel (K1 head)           110.4 grams for 8 (55.2×2)

Frankly, there isn't as much difference between the titanium and the factory steel retainers as I would have thought.

And just to add another data point CycleX sells these for the f2/3 heads, 11.25 grams per come in to 90 grams for the set of 8.

A little lighter than the titanium ones.

Somehow my mind would allows lean towards those retainers breaking due to the holes.
