I have a set of 706 heads that I am cleaning and polishing the ports on, not valve work. I will be having the heads milled. What would ya'll suggest, I want .006-.010" or should I go a full .012 witch will lower cambers 2cc. Would I have to get shorter push rod or will the 7.400 be fine. Will be installing the TR220-112 with comp 918's. Your opinions are welcomed!

I would stick with as minimal milling as possible unless your after a targeted C/R. Its not going to be all that much of improvement and will save you time with finding what pushrod length your going to need when you could just stick with a standard 7.4. Keep your decks as thick as possible to save yourself in the possible event of overheating. :twocents:
