You need to get the spring requirements from your cam grinder for that specific cam. Or have the cam card handy and call one of the big companies and have them recommend a set.

Like Trendz said, the heads have the external lines from the back of the block to the heads. You'll likely have to put restrictors in the fittings b/c w/o them, you'll lose a lot of pressure since it'll flood the heads w/ oil. Normally use .060" restrictors in the fitting on each head.
