Try calling summit or jegs, speak to a sales associate or technical assistance person. Tell them what engine you have and what it's going in.It's not really that you need to match headers to the corvette engine, it's matching headers to that specific cylinder head and and the tubes being bent for that truck. Not hard at all to find I think, just don't wanna order headers for a vette and find they don't fit because they have fitment issues in a truck, being there 2 totally different vehicles.
