no need to. weld your a-arms down to get some height and it will be ok. but make sure you plate the rear humps if you can because they will blow out and when you notch it take a big U out of the frame about 3 inches after the hump and a V 6-8 inches from the rear

this is what i cut out of mine and it was just enough to pull the front a little past level with the rest of the frame

Right behind where your firewall body bolts go, there should be a factory vertical weld. It goes all the way around the frame. Basically just cut the weld on the bottom and halfway up the sides. Drop the front and reweld the cut. It will look stock

here is kind of a better picture for you hope it helps

Does this work

I've also seen it done at the trans crossmember seemed to do ok

When you tilt chevys Do you pull rearend down like fords????

i had to pull my rear down some just so i could get the weight back on the rearend to get it to move around.  i dimpled my frame all the way till it was at a 90 degree angle an then dimpled second spot a lil an then sat body on an it straightened my dimples but when u hit it with a car u can watch it flex bc the frame has so much pressure on it aready
