Have seen a pic and we all know a dud batch of Atomic HD's did the rounds, Nizpro going soft stories remain frequent and now, on the AFF, there's a photo of the Crow race springs with supplied retainers fouling on the rockers and it's not an isolated case apparently.

For my power goal and boost it's marginal but I want to make sure they don't let me down come new tune time. I'm confident the Plazmaman ones will do the job.

just noticed Crow issue post on here also - my bad.

What about pac springs? TBRE seem to use them in their engine builds and recommend them. Never heard anything about them?

I reckon if you search hard enough everythin has a dark side.. they're all pretty reliable just make a decision on which 1 you reckon has a cooler name

I agree.

Pac springs are USA and very good reputation. Only thing is new to market for our engines and I believe they run a pretty firm seat pressure - 100lb+

PAC Racing springs it is, lol. Getting fitted next week.
