Valve Springs

Any thoughts on manufacture, spring rates, dual/single/damper, etc?

I have a hydraulic lifter setup, with E7 heads, net lift 0.4409" cam with 280°/280° advertised duration, early 351W valves (1.84/1.54) coupled to a 302 1970 block.

E7 installed heights are 1.78 in and 1.60 exh. I'm waiting for test data on their loadings. They are single springs

1976 spec 351W was 1.79 in and 1.79 exh with mean 75 lbs installed and 200 lbs at 1.34 valve open.

Re: Valve Springs

I like doubles as they have wider harmonic stability..I guess this is a flat tappet cam ?
If heads are off ? Machine for higher instal height so Chevy springs can be used...Plenty of combinations that way....
