got a question for you guys i read that you guy use 304L sch10 stainless to make manifolds was wandering if anyone had any problems with it cause i was thinking about buy 316L sch40 a little thicker and stronger metal or am i going overboard.
and where can i get stainless B series head flang.

 

sch. 40 would be heavy as ---- and sch 10 is all you need should be sturdy enough for what you want to do and as far as a b head flange look here.

ok im going to try out sch10 but i cant find any stainless head flange for a b series at http://store.racing-solutions.org/
they have 3000gt ford and a cuple of others but no b series

 

i though they had them sorry try emailing mike at LSD here is the link

buy a bmc flange, youll thank yourself later. mikes flanges are covered in scale which is supr hard to grind off and have the lange weld well. also more than a few that i used to get off him were warped as ----.

 

but there cheap....

get what you pay for i guess

 

I've never had any problems before.

 

lol, and you knew 100% well they were warped but you said it wasnt a big deal, i wouldnt havent even sent them if you werent desperate for some flanges. Lastly, it takes a total of 5 minutes to clean the flange on a belt sander... you can really rape the side your welding on because you can afford to have that side a little uneven if your going to weld on it and seal it up anyways. The Stainless Flanges are $38 shipped.

As far as the piping goes, sched 40 really is overkill, just spend the time doing the sched 10 right and you wont have any problems.
