I have, I was talking to them about doing twin 660's possibly. For the power goal I'm thinking of now (I've changed my mind a few times already, ha ha), I will have to go twins.
As for cams, I've been kicking around the idea of doing the HKS vcam pro, but it's expensive, so I may just do some 272's.
Since you have the head out, may want to go higher on the lift, which typically requires some head work. Duration doesn't help as much, at least from my experience, it just creates lag. Not sure if you have seen my build posted at another forum, I went with Tomei 256 on a low hp but quick response build, and I seriously could do without the cams at all.

Interesting, I'll have to do my homework for sure before I select cams. I run 260 12mm lift cams on my SR and they have been awesome. I definitely agree, lift more than duration is where it's at! From what I can tell, RB cams typically don't have a whole lot of lift, so I was thinking I'd have to up the duration.

Yeah factory cams are 8.58mm IN and 8.28mm EX, which are pathetic. I went with Tomei's 9.15mm, which is still pathetic but at least it's guaranteed no valve float issue or require any head work.
