need headers

ScampMike. No racing. May take it to see what times it will run when I get it straighted out. Just a toy. Had a 72 Demon 340 4 speed 8 3/4 posi when I was a kid. Wrecked it. Had a 73 dart sport 340 4 speed posi. I sold for $1400 when i went in the service
I found this car. Body and paint great, and I hate working on that stuff. I like playing with the other stuff. I found a 8 3/4 489 case with a posi in it. Put new gears in and axles. Now I'm working on the power plant end. I ordered the TTIs.
Cam and heads next?
