Yes, extremely, make sure you get as much as you can, orignal wiring harness, pedals if allotted, as much hydro stuff as you can, electric fans if he'l letcha take em too. I'd get what you can because the price is good, but make sure your budget can take everything else your going to need, look at that list on mie and you'll see alot of stuff you'll probably need, including the rewiring of the harness to remove the VATS extra 02 sensors ect. Talk with jesse @ www.wait4meperformance.com or you can ask around on here or ls1tech.com to see whos done it themselves and how hard it is.
Good luck
