Trick flow heads how are they ?

Thanks.

I had 1 3/4 with the 360 but the new 394 it has 1 7/8.
Cool thanks for the info. Was the 1-3/4 of the shelf header or did you have to have some custom made? My son found me a 1-3/4 weld up your own fender well kit for $450. But I have never built a set of headers before.
