1.What drew you to this style head?
I was running out of 781 and 049 castings in my engine building buisiness.
2.Did you have to replace the exhaust seats?
No, on muscle car builds I do not replace seats, but I'am a fanatic on round strait properly sized and finished valve guides which lets me make a very concentric seat with a extremely nice contact patch that transfers heat good due to the valve setting down on the seat perfect every time. Tow applications get a 1.750 CHE exhaust seat.
3.How much do you think you increased the volume when finished?
I don't know I didn't check it, I machined, built, dyno tested, installed it in 7 days.
4. Did you have to fill the intake manifold to match, or was it close?
No, I smoothed the plenum divider, the intake is not the cork.
5. I have built tow engines close to this, this engine would be good in my dualie, except the 9.3 comp would worry me along with the 1.880 exhaust valve size. I will put a link up to my 489 tow build along with a picture.

6. Last is that Scott Welborns old car?
Yes, I bought it from Dale Hulquist the BSer, when it arrived I realized it would need a total rebuild from front to back, and thats what it got.
