I appreciate both of you helping me with my questions. I did upgraded to roller rockers a couple of years ago. So I could run a beehive spring as long as I run a steel retainer? It would be nice to run a smaller and lighter steel retainer on the nose for some more ponies!

Jimmy told me years ago about angle milling the 401 head to get it down to closed chamber CCs. .125 off the bottom at 0 on top, redrilling head bolt holes, etc...
