440 TNT rebuild

What brand lifters do you guys recommend to use with Comp 268/280 Lift .477/.480? Reading many horror stories about wiped cam lobes probably due to poor Comp lifter quality. Thanks.

Compared singe and double from comps and 440Source (dont know what spring brand they sell with theire heads)
