273 Engine intake upgrade turned sour

Thanks, thats an old video, I have an idle one somewhere. They should be cup/ball pushrods. Give them a good check visually and also roll them on something for perfect straightness. Make sure the adjusters in the rockers are snug, they have an interference fit.
She sounds awesome! Especially since you still had some tuning left to do! Thanks for the help! Should I keep the same pushrods as long as they check out when I inspect them or is it best to just replace?
