Default PR length question
So i bought a MS cam for my car (243 heads and stock everything else) I am putting in Patriot gold springs and have bought 7.4 hpr's from texas speed. Are they the right length for the cam? Per my reading it seems i should be okay but i dont want to get half way through my install and not have the right ones. Any help or advise would be appreciated.

most of the time with stock heads you want longer pushrods since the aftermarket cams have a smaller base circle.
