Which roller rocker company should I get, I'm very familiar with Comp, but I'm not sure what is a common roller rocker that you guys run on the L67's. I'm either going with a 1.9 or a 1.8 and does anyone have the specs on the rockers for when I order them.

Get 1.8 if you want to keep stock valve springs. If you upgrade to 105's and want to shift higher than 6k then get 1.9's. I will be 1.9'd next year.

i like my yella terras, they have a 1.95 option. aftermarket springs with the 1.9's are very debatable. I believe you need springs with 1.95's.

You need springs with 1.9's unless you want your stockers to bind and break on you. You wanna get technical, 1.84's are the highest ratio you can run on stock springs.

as i said, there is alot of debate, some guys use them with no problems, no float on stock springs, others upgrade the springs. I went with L76 springs on mine just to eliminate possible further problems.Originally Posted by OH4CompG

Upgrade the springs anyways? If they're old you should change them anyways. If you want to rev higher, you might as well.

with rollers you need to run bigger springs with anything over 1.8s. if youre going the roller rocker route and have committed to it then i would definitely go 1.95:1 ratio. otherwise just save yourself some money and get the modded 1.9s.

what about the zzp er rockers for the n/a set up. if i put those in and new springs...how much higher can i raise the rev lim?
12-04-2009
this. the modded 1.9s seem to be fine on the stock springs. but rollers is a diffrent story.

How much of a pain is it getting to the back springs? I really don't want to tear the motor down to pull the heads off. I know I can just raise the piston to the very top and let the valve drop, but wouldn't it be a pain since the supercharger would be in the way? I apologize for the dumb questions, I usually only toy with RWD V8's and I know these motors can be a little bit touchy sometimes.

its not all that difficult. just gotta reach. you probably will get cramps and anoyed from bending over and reaching for so long (damn that dident sound good) i had to take a break or two doing my rockers

true story.

nonsense... hop up and sit on the motor, it'll be fine unlike your back after and hour.

^^Agreed. Spidermonkey that sh!t

IIRC it's not about the float, it's about the amount of compression a stock valve spring can take before binding.
