will modded 1.9's hold just as well or close to the quality of what stock is? and anyone have expirience with the modded ones? im looking to order these tomorrow just trying to get opinions. 3.4 pulley, custom tune, headers, catback, 104's, 180* tstat, open cone, hydaulic lifters, comp push rods and 1.9rr is what will be installed when its all said and done.
 


since they are stock rockers, just a new pivot point made in the rocker, they'll last forever just like the stock ones.
 
Haven't heard of anyone having issues with them before.

Very glad to see you're going with hydraulic lifters as opposed to solid lifters, those wouldn't be very good in our motors.

I'm assuming you mean new lifters? any reason. Should be a stout little car with those mods.
 
I have a local that has had 4 modded rockers break over the last 3 years. Keeps having to have ZZP send him a replacement. Modded rockers aren't roller rockers by the way.
 
Would have to ask the local guy if he had any pics of the ones that failed....believed that the welding that was done to modify the stock rockers cause the metal to become weak, ended up causing stress cracks that eventually failed.
 


Dont bother with pushrods and lifters if you arent going to do springs. Without springs you will get valve float just before 6k rpm. No reason to have lifters and push rods if you arent shifting above 5800.
