Don't sweat the small stuff and just get it done. It's to the point that all of the analyzing you do as far as what works, what doesn't work, who is right, who is wrong, this is the popular opinion on this or that has consumed your ability to complete a project. Do yourself a favor and log off Moparts for 2 months and just put your car together and drive it.. At the end of the day nobody really cares if your pushrods are .003 too long or if the BLP main body has no definitive data on it's flow numbers vs Proform... Life is short.......... Get er done!!!!!!!!!!
