Roller lifters: Hyd or Mech?

[srv1]

i have a dilemma. i need to put new lifters in my car. what name, type, and why fo each one to use. basically i want to run mechanical rollers for durability, but i dont know if they are good for longevity. do i use a roller cam? or is their a roller mech. cam?

i figured that if some reason the hyd. lifter fails, then i would have to replace it. and that can be a pain in the asz. what i want to do to my car for now, is use the Track Heat intake with the 70mm TB with the stuff i have below. i dont have money for heads right now, if i did, trust me they would be in! also what size Mass should i use? i will be using my stock 19's for awhile and i dont see me getting 24's anytime soon.

my plans for the car is street driven and an occasional trip to the track. i will be setting my car up for SCCA.

i dont mind the noise of the lifters and also down the road if i get sick with the injection i will go carb.

how often do you have to adjust lash on the mech.? if i can use mech. for everyday as if they are hyd. then i will use them.

thanks, James
