Dave thanks heaps for the info and taking the time to put that up it helps alot as i am really new to this and it sounds like i will need to just keep an eye out as i have a speco tri manifold and cover and would like to match the headers with it and really stick to period mods only and give it a feel of something that could have been a racer in its day and then stuck in some shed let to age alittle
And i did checkout the aussiespeed site and see that they are going to remake that type of header and it may be an option but cant say im too keen on their logo
