no they wont, series 2 valves are metric. small block chevy valve srings , retainers, and locks are a direct fit for our series 1 motors.
i know this first hand, thats what i have on mine now. 110# @ installed height 1.750"

Also, why are you running 110lb. springs? All that does is make it harder for the valvetrain to push the valve open meaning you will get a little less lift and more strain on the valvetrain. We were going to put 105lb springs in the GTP, but Zooomer said that would be overkill, and if we wanted performance the 85lb. would stop the valve float and not kill too much lift and put too much more stress on the valvetrain. I am just wondering if there is some reason I am not thinking of why you are running those springs.
But, if you can get the rockers made, that would be awesome for the Series I guys. Should really wake up the topend power.

i went with those spring due to my experience with racing sbc engines. the series 2 springs are conical. ours are straight.
as far as the 93-95, i need to check ARP and see if they make screw in studs with 5/16" bottoms and 7/16" tops. my 92 has 3/8" bolts holding the rockers in place and it has a flat steel plate with guide plate slots cut in it. comp cams makes studs with 3/8" lower and 7/16" tops. here is the reason you need 7/16" tops. the HI TECH stainless rockers are the only ones that come in the 1.8 ratio. and they are only in 7/16" studs.
i used a 93 rocker to get my measurements . so if you find the proper studs, they should work too. i checked with NAPA and the pushrods are the same from 92-95.
93-95 do have roller fulcrum rockers, but they still are only 1.6 ratio

Hey, when you get that done, could you list out the specs and #'* for all the parts so we can see it easier? Maybe we can do a TechInfo write up? :?

Any update on this? I'd like to be able to do this in july at bonniefest, or before hand. Maybe a Run without, then 3 of us converge on the pearl, throw them on, and do a run with it.
