I'll be running a solid flat tappet cam and although I'm not quite sure of the exact size yet it will be in the .560 to .590 lift range.

If thats all you ever plan to do, use the comps, you will never hurt them and never worry about too much oil up top or needles in your motor.

If you plan to go heavy roller, high rpm HS.

Money is money I dont spend more then I need to, but thats just me.

Even the $500 china SS rockers that people use and ive heard nothing bad about would work in your case, not the al/needle ones the SS bushed units.
