Ken, solid lifters are only needed if you intend to rev the motor, for all practical purposes, past 7500rpm as you stated below. Theoretically there are weight savings to be had by going with light solid buckets over oil filled hydraulic lifters, but then you need to deal with frequent lifter adjustments as the sold lifters wear. Also, with ultra high lift cams solid lifters are more durable and can stand up to the abuse, plus you may need to upgrade the diameter of the lifter to keep the cam lobe on the lifter, in which case a larger diameter bucket (with associated machining) is a must.
Realistically, lifters won't be much of a power/tuning endeavor, it really depends on what you intend the motor for, for an all our race motor it would be worth on, on a street motor I'd concentrate on other things, but if you want to go all out, its a good thing to upgrade. Eurospec has complete kits we developed, they use a light bucket with a valve-stem lash-cap for adjustment, all compatible with the hydraulic lifters, not sure what the price is, but its listed on the site.
Again, its one of those things that have diminishing return, for a smooth, quiet, maintenence free street motor hydraulic lifters are fine.
Anyone care to share their experience with upgrading lifters? -I'd be intersted to hear what's been done.
