What Valve length?

Hello,

I was wondering what valve length I needed to run with my setup.

Here is what I have:

Procomp 190cc heads. 2.02/160

Competition Cams 12-224-4 Camshaft

Manley Valve Spring seats: 1.300" ID, THE LOCATOR .650" the ID .500" .065" thick.

PSI 1.300 Chrome Silicone Valve Springs 350 @ 1.500" ID: .605 Seat Load: 150@ 2" Open Load: 350 @ 1.500 Coil Bind 1.150

I have not bought the locks yet, and here are the choices that I have:

Del West &Titanium +.050 valve locks for the Super 7* retainers in 11/32"
Del West &Titanium -.050 valve locks for the Super 7* retainers in 11/32

I was just wondering what valve length I needed with this setup, stock, +100? Also, would the valve length be affected by my decision to buy +.50 or -.50 locks?

Thanks,

Han

Okay, just wanted to make sure I am looking at all of this correctly.

If I install my springs at 1.800" with this cam I will have .125 before coil bind?

I calculated this by seeing that the cam lift is .525. Which would be .25 more than the valve seat and open lift.

Now I could get the +.050 retainers and have .175 before coil bind correct?

So my best bet would to buy +.050 retainers. After thinking about the .065 added by the valve seats would it just be better to go with the +.100 valved and the stock valve locks?
