Valve lifters

[Johnny Jimenez]

Hello, I have a question, I purchased a 2004 suburban 8.1L 4x4, with 90 thousands miles with a bad engine, I got everything but the valve lifters are bad and I need to replace them,  my question is if I have to use AC delco, or I can go with Melling JB 7003 brand or Comp Cams 900-16, or Martins brand, Perfect Fit, Lif3181, is so many options, some really expensive like AC Delco and others very un expensive like perfect Fit. 

I will appreciate any professional information.

thank you.
