Hedman Longtubes + AFR angle plug heads???
Will Hedman longtubes work with AFR angle plug heads? I looked at Summit and it said they would fit angle plug heads, but I didn't know if AFR's have a different angle than the L98 heads or something. Is there anybody that has this combo? BTW, the heads are AFR 190's if that matters.

Just so you have more info on it, AFR has 3 types of heads. Straight, angle, and L98 angle.
Just wanted to throw that out there.

Go to Hedmans website... lookup the headers you have and they have NOTES on them... what fits what doesn't, legal not, etc.
That's how I know my Hedman Shorties will be fine with my Pro Topline Angle Plugs.

If you have an auto they should fit fine, but if you have a T5 you will need to bend the collector down to clear to slave cylinder.

I've heard on the drivers side the collector can hit the K member. Might have to do some grinding
