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 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
