What valve springs should I use?

Why are we worrying about cracked Magnum heads? Seems like 80% of all Magnum engines are running around with cracks and operating just fine. I've got a set of ported cracked Magnum heads on a 420HP 360, thousands of miles of hard use with no problems. How many of you 'cracked head worriers' have ever experienced any water leaks from the cracks between the seats or any engine damaged from those cracked heads? Aren't the cracked heads coming off running engines for the most part. I've pulled a lot of 'em off wrecked cars/trucks and they had to be running to get in those wrecks. Just saying....cracked Magnum heads have never caused me a problem.

Dang I was not aware it was that minor of a problem, machine shops and such had told me it was a no-go but if that's the case then hell yeah... I was worried I'd crack the factory Magnums on my 360 but if what you say is true I'd love to stop caring lol

CordobaDart what head gaskets you gonna use? I would use the thinnest (steel shim??) you can find with those dished pistons. I am also running the Hughes 1110 springs on my 360 with their retainers and locks, the engine has at least 20k since I put it together and it still runs great. I should probably pull the valve covers at some point though and check it out, I can't say exactly the condition of the parts but I run it hard and it never makes noises or skips a beat.
