Thanks Charlie! I just ordered the caliper. I think they will work out okay if I open them up a bit. There are some other features I don't like, but I got these headers cheap and they were unused.

I got one of these for checking things like that, https://www.ebay.com/itm/6-Outside-OD-Digital-Electronic-Gauge-Caliper/130526074822?epid=2256189312&hash=item1e63f5d7c6:g:2ekAAOxyaRZR5177

Mummert's rams horns are more like original and do not have that.  So if you can return them, and get a set from John, that would probably be best.

I was just wondering if anyone has ported the end runners on the "Tru Ram Headers" from Speedway Motors. Those two end runners have substantial casting humps that I feel need to go. The outside of that area is concave so you can get a wrench on the exhaust studs. I don't want to make that area too thin and wondered if anyone has done it.

Thanks,
Rono
