Re: bbc headers
I just installed a ZZ502 in my 68 with 2" Hooker comps and they fit great.
It is critical to use the correct frame stands and motor mounts. Check Hookers tech info and installation notes. They only guaranty an interference free fit if you use stands and mounts from Ricks First Gen. I followed this advice and they went right in.
Driver side needs to be set laid in there with the engine up a few inches first, then lower the engine and bolt her up.
Passenger side goes right in from under the car.
I did prefit the headers to the engine before installing the engine. As a result...One thing I did have to do is grind some clearance notches into the header flanges so that the flanges would clear the lower head bolts on my alum heads (hopefully you already did this before installing the engine or you will have a lot more work to do).
Other than that, it was a great fit.
IMHO you should not have to take anything off your control arm bolts. This will kill your ability to adjust the aligment when the need arrises to add more shims and the headers should fit without having to do this.
