Default LS2 Heads and Intake on 5.3

Would this be a good swap? What are the power gains?


Thanks

ls2 heads are 243 heads w/o the light weight valves. you have to mill them to not lose compression. which ls2 intake? car or truck.

for the car intake you will have to make some modifications to your accessory drive. the truck intake will bolt right up. a few differences in evap hose routing and you need a torquerush adapter to use the 90mm t-body unless you are cable driven. but a relatively easy swap. i had the ls2 heads on my 5.3 and am using a tbss intake on my current 6.0.

What kind of power did you pick up with the heads?
