Default 1973 351 cleveland can you ID these valve springs?

I have a 1973 mustang 351 cleveland 2V motor. It has a 750 4 barrel with a weiand intake and headers and a HEI distributor. I am replacing my cam. I would take suggestions for a cam/kit. I am looking at the

Competition Cams Complete Camshaft Kit
Part No. K32-221-3
High EnergyGS=; Camshaft Kit; Hyd Flat Tappet;1500-5500rpm;Adv.Dur. 268 Int./Exh.;V.Lift .494 Int./Exh.;Lobe 110 deg;Incl.Cam;Lifter;V.Sprng/Ret./Lock/Seal;Timing Set;


But my heads were rebuilt by the previous owner. I cannot find him to find out what springs he used. Is there anyway to Identify my valve springs? Here are some pics. I need to know if they are good enough to use with a Comp cam like the one in the kit. If so I will just get the cam and lifters. I already have a roller timing chain and sprocket set. And could save the money for the springs and retainers and such. I am open to any suggestions.

With out numbers I see no way to identify those springs. How ever I suspect they were replaced with oem springs.

For piece of mind ( if you cant verify with P/O ) assume stock oem springs , and get the springs that the cam maker suggests.

man. I am run out of money right now...I am going with a pretty mild cam, Duration 268/268, Lift .494/.494,. Do you think I will be ok for a little while?? like a year or so, just street driving, this is going to be a daily driver car. I have another complete engine, I was thinking about removing the heads and having those heads completely redone with roller rockers and studs and Stainless valves and heavy duty springs, and hardened seats,and polish up the ports some... maybe be able to do that after the first of the year.

Then I may take the spare block and replace the crank, pistons and rods, bore it out some if it is not already and add an oil and trans cooler with electric fans, that would be a real long lasting set up..get my AC going and new interior, finish the body work and repaint. Then beef up the suspension some...crap this is getting pricey....could just buy one already done for half that...LOL

A small cam on stock heads won't really gain you much for the effort and cost.

Just save up and do heads/cam all at once. Avoid problems.

And if you want a cheaper hobby, try coke, hookers or gambling.

if you think you dont have money now wait till you drop a valve, ruin your new forged piston and crack the cylinder wall and have to get a sleeve put in....
