Default LTs and PI swap

If I get a set of LTs now and then do a PI swap down the road with the LTs fit? I am pretty sure that they will fit but before I shell out the $450 for the BBKs I want to make sure. Thanks

if your doing a pi swap you might as well get the headers done at the same time, since the mechanic will be taking off the exhaust manifolds already it should be a little cheaper if you do it all at the same time, and yes as long as you get the headers for the pi heads (i think theyre different but im not sure) they should fit. dont forget header gaskets and a new shorty midpipe.

They should fit only thing to be concerned with is if your car is an auto. Some of the header company's don't make lt's for autos and some do. Just check into it!
