Following testing in our MGB road race engines, I worked with Paul Jette at Del West to produce a couple sets of Ti valves for use in my NASCAR Fords. These were the very first Del West valves to run in NASCAR.

Almost complete....We've modified the exhaust rockers to create more valvetrain clearance after some eyeballing. Finished the chambers (turning the Z6 corner radiuses into larger ones without touching the port floor took the old one a while). Blended the valve seats this afternoon and threw it on the flow bench. Intake airflow is identical to a stock B18C1 with a good valve job! I'm doing this with a throat diameter of 88%, so it's a screamer up to .540" where it levels off. Once we get situated at Mast's, I'll cut the same port in a test head, and see where a larger throat could take it. No experimenting with this one...it's too good.

The 351W turned out to be a perfect match to the broken one it's replacing. Since these racers tend to touch-up seats on their own on occasion, you can see how I eliminate pilot push-off in these applications. If you look closely, you can see how I relieve the long-side of the guide bore so there's no push-off.
