valve spring question

check your used springs what are they now? check at thump lift
thumpers for mopars are mild mopar lobes not chevy lobe and not hard on springs
check but the mopar springs should work
Thanks Proff
There are mild Mopar grinds like the Mild Eggles, Mopar performnce, some Cranes and the Thumper and Purple Plus from Comp and some Crowers, Jones "Motorhome" cam
Lunati voodoo somewhere in the middle
then there are the Comp HL and Howards which have more lift but not really radical
then there are race only lobes
Still wonder why anyone would need that exhaust split even with stock heads and manifolds I'd watch my exhaust temps if any heavy use
