Anyone running >.630 lift I was wondering who was running .630 lift and greater. (1.7 rockers)
What set-up are you using for the rest of the valvetrain? What springs/longevity issues are you having? Have you been able to run the motor high in RPM without valvefloat issues?

Jason98TA I will be in touch for the heads.
For those of you that use this lift are you experiencing and issues with excessive spring wear? How high do you wind the motor? How often is it checked? I know that some of you are constantly into your motors but just curious as to what limits there are in some areas. With the springs I have the crane duals rated (BY THEM) for .650 lift. That is free torque for those that wish to deal with the spring issues.

I havent run mine yet still sitting in the shipping crate, cam is .6307/.6222 231/242 114*LSA 111*ICL. PP Gold Springs, Morel Hyd Lifters, TR Pushrods and Stock rockers, stuffed into a forged 347ci chunk of aluminum waiting to be fed some mild doses of nitrous. Cant wait.
I am going to guess depending how long the springs see the higher rpms, and the frequency of those visits will determine how long they will last. Like any other spring, if you keep it rev'd for long durations you'll lose longevity.

635/627 here. I'm using the PRC dual springs, TR pushrods, stock lifters and rockers. I barely have any miles on this setup but I'm not expecting too many years of life out of these things.

Lobe#, Dur. @ .006", .050", .200", & Lift w/1.7 rocker
2124 265 215 142 .629"
2125 269 219 145 .632"
2126 273 223 149 .636"
2127 277 227 153 .639"
2128 281 231 156 .643"
2129 285 235 160 .646"
2130 289 239 164 .649"
2131 293 243 168 .653"
2132 297 247 171 .656"
2133 301 251 175 .660"
2134 305 255 179 .663"
2135 309 259 183 .663"
2136 313 263 186 .663"
These are the LSK lobes. I believe they are in the new master catalogs. Very very agressive. The 239 at .050" LSK lobe is bigger then the 242 at .050" XE-R Lobe by the .200" number.
