Wouldn't a vendor like ZZP already HAVE dyno numbers if they advertised a claim like that? I would assume it would be a very simple matter to ask ZZP for the dyno data and get it. Are you speaking for ZZP officially, or do you not believe they have the data?

My suggestion to any member here would be to contact ZZP in the interests of this topic, get the data, and post it for the benefit of those interested. After all, this is the bulk of the Series 1 L67 market.

I bet that these are Yella Terra rockers since ZZP worked with Yella Terra to lighten there rockers and create some custom ratios (1.84:1, 1.95:1, etc) for the Series II.
With that being said these look like older Yella Terra rockers which would make ZZP a distributer or the rockers. ZZP being a distributer of the rockers I'm sure that all the data has come from Yella Terra.
ZZPerformance is the only 3800 vendor with an engine dyno but I'm more then willing to bet that these rockers have not seen a dyno or even an engine by ZZP. For the amount of rockers ZZP is going to sell it really doesn't make sense for a company like ZZPerformance to dyno these rockers for themselves.
Just my .02
J. Wikoff keep BC updated to see I'm on track or way off.

have different rocker bolts than 93-95 L67 and 93-94 L27 3800s)?

Let me know if I should make another thread...
I have LN3 heads. Would I gain any more HP if I used these rockers on '95 heads with the roller tips versus the LN3 heads? I'm not too knowledgable in valvetrain, but wouldn't the ZZP rockers have the roller tips that the LN3 heads lack, and therefore, it wouldn't matter which I installed them in?
