Stock valve springs?
I'm planning a head/cam swap. I've got the funds for the cam now but can't swing the heads until early summer. I'm doing the work myself so labor is not an issue. I'd love to put the cam in now, but how much can stock springs take? I'd also hate to change springs now and heads later. I've read several threads discussing "stock" heads, does that include springs? Thanks a ton.

the stock springs can't handle much more than a stock cam. plus, with the added age and mileage of the current stock springs, it's not advise able. stock springs are 85# seat pressure when new. most aftermarket cams need at least 112# seat pressure.

To really take advantage of a new camshaft, the springs must be matched to the profile you've selected. As pointed out above, more radical valve movements combined with aging stock springs will not give you the best results.
At best, you can expect the operating range to fall short of what's intended to due valve float or loss of valve control. With bigger cams, weaker springs (or both) you may damage the valvetrain or pistons. Springs and retainers are cheap insurance when swapping cams, and will be necessary for the most power out of your cam.Hammer - hammertime.us

Thanks. the car has 12,000 on it so springs aren't completely clapped out, but I also don't want to tear anything up.If I have to I'll wait on the heads. Thanks Again. Also not decided on a cam, still sorting it out.
