Guys I certainly appreciate your input.
I've read horror stories on various forums of cams failing prematurely. This is why I'm trying to go about this build as meticulous as I can. I've read about cam break-in procedures at-length and hope to follow the guidelines provided here and elsewhere.
There seems to be differing opinions on the valvespring issue here. Here are the specs of the springs provided with the heads:
Intalled Height (Intake): 1.88 (Exhaust): 1.88
Seat Pressure: 130
Open Pressure: 320
There are various check boxes with the different types of cams on the spring card with "Hyd Roller" checked.
Lunati's recommended valvespring specs:
1.266 Dia - single spring
Installed Height: 1.75
Installed Pressure: 108
Open Height: 1.25
Open Pressure: 339
Coil bind height: 1.060
Spring rate: 462 lbs/in
I realize we need to compare apples to apples here, but the above info is what I found on both springs.
Judging by the numbers, the provided springs are obviously heavier. So F-bird, do you think that these will be OK for my cam? My line of thinking is the fear of having too much pressure on the lobes. You suggested removing the inner springs. What are the specs of just the outers? Are they similar to Lunati's recommended specs?
454C10, you recomment NOT removing the inner spring, right? What would your alternative be?
I apologize for the redundancy. I just want to be confident before I start assembling anything.
You all have already been a big help.
