Default Comp 921 springs

How many out there are running these springs? What cam are you using?
Have you heard of any failures?

These springs are suppossed to be the cats azz and one of the top dual springs that work with stock heads without extra machining, etc. The problem is they are so new they have not been battled tested yet and we have to give them several months to a year, etc. to see whether they stand up as well as they are "hyped/suppose" to, etc. If i was going with an aggressive cam with stock heads either this or the new patriot dual gold drop in springs would be my choice!! :cheers:

We've been running the Patriot doubles with titanium retainers & seats for $299, or we also do the crane doubles with titanium retainers. Both have worked well for us & are priced very reasonably :)
