Critique my mismatched Teen Build.

Ok.. so I would certainly be happy to look into stepping up to a solid cam and lifters however my question would now be this...
Would the Edelbrock 'Sure Seat' Valve Springs #5767 as are currently on the heads, be usable on any of the following camshafts?

Comp 270s - I suspect this one would work as Comp specifies the 901-16 Spring which I think the Eddy spring exceeds, although they do not list a spring rate as such?
(This is a small solid but I suspect it would probably still out perform the Xe262 hydraulic and still run with a stock converter.)

and the Comp Xs268s and Xs274s - Not sure the Eddy springs could control these cams?
So I would also be up for new springs, retainers, locks etc.

Eddy Spring #5767 120lbs on the seat 310lbs open (0.580" lift) and as I said no spring rate stated.

How many are running the stock springs on the Eddy #60779 Heads?
Guessing not too many.


Cheers,
Teedog
