Valves, And Springs

[Super White Alero]

K, I decided that I will finally turbo the ho. Problem I seem to face (other than cash flow) is valves and springs. Factory spec on spring is as follows:


valves and spring

spring pressure closed: 50-55lbs @ 1.44"
spring pressure open: 122-133lbs @ 1.06"
spring diameter lower end: 1.2018"
spring diameter upper: .8XXX"

Intake valve
length: 4.227"
installed height: .9787"-1.002"
head diameter: 1.396"-1.399"
stem diameter: .2331"-.2339

Exhaust valve
length: 4.259"
installed height: .9787"-1.002"
head diameter: 1.137"-1.147"
stem diameter: .2326"-.2334"

Deciding to purchase from comp cam (http://store.summitracing.com/default.asp?Ntt=valve+spring&x=0&y=0&searchinresults=false&Ntk=KeywordSearch&DDS=1&N=115&target=egnsearch.asp) but first I need to know is these springs will work or not? Secondly does anyone know where I can get some lighter valves?

Spring pressure seated: 75lb
spring diameter: 1.159"
coil bind height: 0.964"
spring rated: 228lb

And my final question, (Germ you might be of help here) can I use factory torque spec on the head or do I need to torque further running boost?


Thanks
