Couple questions about eq heads?

I sent Hughes an initial email with my drive train specs and What I was thinking about for a potential cam change. Tim got back to me that afternoon with suggestions for my stock magnum heads. I then called and spoke to him directly. He put together a parts list for the cam and upgrades I decided on and I added some things to it as well. In the end I got a camshaft, spring and lifter upgrade, stem seals and a new timing chain kit. He was great to talk to and answered any questions I had about the install.
