Can anyone guess my valve springs?
https://drive.google.com/file/d/0B4m...ew?usp=sharing
I got these LE3 heads. But I don't know what valve springs are on them. I don't think these came with the LE3 head package. I see three springs in there. The middle one being an odd flat spring. Any help would be great!
Looking to use Lunati 20080723 / 60123 SBC LT1, LT4 Hydraulic Roller Camshaft RPM Range 2800 - 6800 Lift .560"/.565" Dur.@.050 243/251 LSA/IAC 110/106 in a 385 with 12.1 static compression. Then add 1.6 rocker to get .597/.602. so im hoping these are hydraulic springs.
Thanks
Derek

Contact Lloyd, he may be able to identify from the pic
otherwise pull and measure open & close pressure at x.xx" installed height (assume 1.80"). measure for coil bind
if the springs spec out to whatever spring your cam card specs, than they would work.
need to confirm they can take the lift your cam makes with 1:6RR
