I just received a set of LS conversation headers from Speed Engineering and I could not be happier. For those not familiar with my project, I have an 84 Z with a complete 92 Corvette suspension and a 408 LS2 which required a one of a kind fabricated k-member which should have complicated the installation of these headers. I had them mocked up in 2 hours (I had to remove the spark plugs, coils, and valve covers) and they dropped right in. The headers fit amazingly well, I will have to reroute my fuel lines, hydraboost lines, and oil cooler lines, all of which is my fault. The quality of these headers is outstanding with features found on far more expensive headers, speaking of which, they cost a third of all the conversation headers on the market. This has been the best purchase I’ve made for this project considering fit, finish, and value, with tens of thousands of dollars invested in this project, that says a lot.
