I don't know about the heartland, wherever that is. I wasn't happy with my old school racing shop in Denton so I can't recommend them. I got no response out of the Self's in Durant, OK. Wouldn't return calls or emails.
"old school race shop in Denton".. you mean Calvert's? They (wayne and louis) used to race a flathead eating 216 in a dirt car in the REAL early 50's. They younger brother (Wayne- I think) seems as reasonable as you could ask for. He is probably 'way past 70 by now -maybe the son runs the place now. Are they problematic these days?
