curious what the weight is? I'd imagine because of the increased weight you'd need to run an even stiffer valve spring to account for the polar mass of the arm rocking back and fourth on the shaft.

look for Lester Owen...

really only a 8k+ need for these 'uns.

But GORGEOUS. In that industrial sorta way.

Hey T . . . for reference, my IE heavy duty rockers saw 8K+ a few times at our race in Las Vegas* this weekend - lots of high-revving throttle blips and downshifts (fair to say the driver was really wound up). I spoke with Lester about the steel rockers a while back, they were available for sale direct when he was making a batch. I believe there's a retailer on the East Coast who sells them as well.

*Re: VARA race at Las Vegas: It was good to Mark working-off his rookie stripes in that feisty 1600, and Chris from Only02 who stopped by - lots of 02 talk with Matt (and Tom) from Ronin.

That's good to know, Ken- I put a set in last fall, but haven't tested the upper

limit as that motor's gone squiffy.

They really just don't compare to aluminum- it's like going back in time, not

forward- and yet they are reputed to be indestructable- as in, you break the

head bosses before you break these.
