I was looking at the the Harland Sharp 1.7 rocker arms after I get the Hughes Intake and Fastman TB done.
My questions are what are the advantages of this mod and what else would I need to make sure it gives me the most bang for the buck. I read somewhere that if I do the 1.7 rockers that I should change the springs too

Thanks in advance

You won't need new valve springs just going with the 1.7 RR's, stock valve springs are good until .480 lift.

A wide band 02 gauge would be a nice opt and then a SCT tuner, they work hand in hand the wideband gives you info that you pass onto the person writing the prog for the tuner.

Basically increases the lift of the cam without doing a cam swap.
