go with the WP heads if you are allowed to. They flow more out of the box and already have HP parts, Springs, retainers, keepers, ECT. By the time you build a set of hump heads up to the WP specs you will have as much in them as the WP cost new ready to bolt on.

Totally agree with spanky you also have to worry about the unknown factors in the old heads IE overheatingor other abuses that will show themselves always go with a new or improved product if possible
