I need an intake and exhaust valve with the springs, bottom and top retainers, and keepers for those valves so I can have a company start making them for us....any takers? they will run about $325 for the whole setup if can find some parts for him to measure off of

 

what will be different about the new ones?

 

can handle aftermarket cams and boost....stock springs/retainers werent meant for boosted applications...if you send your ecu out to jet to be reprogramed you can run higher rpm....they are also insurance for mis shifts....they also lighten the valve train
basicly go online and research why....there is to many positives to not upgrade

 

Yeah I know the benifits i was just wondering if you knew the specs of the new ones. I cant offer my valvetrain but Id buy that setup if someone made it.

 

the specs wont be known untill he can put the factory springs into his machine to get the factory spring specs...he understands the balance in making a great spring and over doing it causing premature wear on cams and rockers....ive been using his springs and retainers in quite a few motors and havnt had one failure....he also builds springs to spec for people who run special setups or have crazy ramp rates on the cams....he currently in house makes over 30 different types of springs and retainers
ill know the seat pressure and spring rate once he has the oem ones to go off of
how many grams of weight he can save off the retainers will be another spec i can give once i can get parts in his hands
