Does anyone know who makes APS head studs. Now, I know it's APS but what's the whole company name? I'm trying to find info on them. A web page would be great if anyone knows what it is.

I believe it is Automotive Performance System, but I'm not positive. <img src="confused.gif" border="0">

Would you even consider anything other than Dilivar or raceware? This doesn't seem to be a good place to try to save 10%.

Avoid the Dilivar.

This topic comes up quite a bit. It seems the two solutions are Porsche steel studs or Raceware. I would love to use Raceware studs, but they are not cheap. While there might be other manufacturers with quality product I think it makes sense to stick with the proven winners.

Best of luck
