wasn't sure where to put this question so apologies if its in the wrong place
Right, 2 dilemma's
1. I currently have a pair of new Dougs ceramic coated longtube headers 1 7/8" primarys that I intend to put on the new 502cuin when it gets here.
Engine will be dyno'd when finished using whatever they dyno it with.
Do I, purchase new headers over there and have it dyno'd with whatever I purchase job done, or fit what I got when it gets here and rolling road it when engine fitted using current ones, it will be rolling roaded anyway.
2. If I purchase another set, "Shorty or Long tube" and biggest debate "what make??" shorty will make better clearance generally, although shorty might restrict breathing , car is low low.
I purchased the dougs as at the time (5 years probably) they seemed to be the way to go for best fitment issues on a breathed 440 and supposed to be good quality.
any advice appreciated

IF ITS ON WHEELS, LOWER IT!!
Re: CHOOSINGS HEADERS
Personally TTI are the only headers I use now, long tube for best performance and no grand clearance issues. Everything I've read about ceramic coatings say don't break in the cam with them or you'll ruin the coating, I assume that's due to getting them very hot before a few heat cycles have settled the coating. Dyno time would no doubt be the same. Normally they use their own "dyno" headers anyway, there are fittings welded into the primaries for probes to give you some of the information you get on the dyno sheet.

If they are rusted through, not a good idea to media blast, good steel will be fine. If you ha e access & they fit in the cabinet, a vapour blaster is kinder & leaves a nice closed pore finish.pete walton wrote: ↑Fri Aug 07, 20 8:57 pmI googled the backside out of the subject after our conversation the other weekend Blue ,I am going to dig out the headers that came with the car and see what make they are …..they are a bit crusty but might be salvageable ...Is it a goo idea to get them blasted ?or will that damage them …...
