.030" longer push rods and where to find them.

In 2018 when i assembled it i couldn't find stock hold downs or spacers so i ordered stuff from Mancini and it seemed to work but started getting noisy at the end of last year. I think these spacers O/d aren't large enough they just don't seem right.
My parts should be here tomorrow and ill go from there oh yeah i also was pricing roller rockers and yeah can't afford them at this time.
