Looking for a few things to do today and I thought I would revisit the header collars. Couldn't work out how they got on there if they wouldn't come off, something must have got gunked up over the years.
Method 1: big bloody hammer, chock of wood and a few good swings. Got the collars half way off the end of the header but that was about it
Method 2: angle grinder!
That one worked a treat, however the enevitable consequence is my collars are now ready for the bin. I am not convinced the stock collars will fit my aftermarket headers so I will be looking at getting something fabricated like these:
Looks like the header has taken a whack at some stage, the lower section is crushed and there is a crappy repair where the 4 pipes go into 1. Looking to have a custom muffler bent from the same mob that did my frame piping, so will probably get them to bend a replacement section for the header too.
Anyone know how to identify the material the headers are made from, its got a brown slight tinge and doesn't get rusty, I am guessing stainless.
Also had a crack at cleaning the valves, they have some serious caked on crap on the each side of the face, how is it best to clean these up?
