rocker problems

Which commando heads did you use? The ones I have are MP# P4876310 and the Harland Sharp rocker # is 70026w2k100. I might just have to take my engine apart and try them on it, I was hoping to get everything figured out prior to taking the engine apart that way I could still drive it until I was ready to switch it all over in a day, but like you said the pushrods might not be correct either. Thanks for your info, if you can think of anything else it would be appreciated.
