I'm Awesome
Has anyone on here messed with porting/polishing their stock lower intake, tb and heads all together? If so we're the results noticeable enough to spend the money on? I just can't justify the cost of an aftermarket intake for the vortec heads and I doubt I will exceed the stock fuel system with the newer mpfi spider upgrade and a fresh pump.
I know a guy I had do my 5.3 heads for my LS motor I built, just wondering if it's worth the hassle.
