The castings are delivered to me in raw form. I machine the cylinder head to meet exactly what i sent to NHRA. There are 3 machining operations that cover the 3 cylinder heads i submitted, 283 thru 327 (small seat dia), 327 thru 400 (large seat dia) and LT1 (large seat,center bolt cover and water holes).
I will be posting a picture later of the valve bowl with seats installed to show how moving the seat and guide location would require welding just like it does on the 4 other replacement castings.
