Thanks gents for the info. zdude1967

I am installing headers, 3 into 2's on my 1974 260z. There are some differences such as the headers do not have the 6 tubes that extend into the exhaust ports, from reading some other treads I think these are the smog tubes. On my original manifold these were cut and welded shut So I assume this means there is no problem with not having the tubes on the headers as I guess the smog is disconnected. Is this correct. The other difference is the original manifold has the tube for the exhaust gas to recycle -the headers do not. What do I do about this. Any suggestions Thanks zdude1967

Thanks everyone for the help!! zdude1967

Quick follow up question. I planned on storing the carbs in basically the same position as they are in when installed. Bob is this the position you are suggesting? Also I have a bad history with ez outs if I break one anybody have a suggestion where it should go in phoenix for professional removal zdude1967

Thanks for the information. I am installing 3 into 2 headers with a 2.5 inch pipe and flowmaster muffler. I have the headers already but am open on the muffler. Any suggestions???

I am putting on headers and will need to remove the exhaust and carburetor manifold for the new gasket. I want to make the process as simple and successful as possible and want to be able to just bolt the carb manifold back on, start the car and go. Is there any special process for handling the carb manifold, such as storing with the carbs facing upright or any other thing I should know to make carb and manifold removal and re-install successful. Will I need to re-adjust the carbs after the go back on? G
