Old Yeller vs Drag Truck "2021"

Hey! Your welcome and anytime! Let us know what that final offset number comes to. Heck of a job doing that work. What steps did you do to plug the pushrod hole?

When I seen Steve Dulcich do that to his Edelbrock heads, I thought about it. Then @pittsburghracer comes up with more pictures, (Thanks Pittsburgh) now I’m about willing to try it myself. Once I get reset up, now think I’m going to try that and make my own flow bench.

To plug the holes, I reamed them to 9/16" and got 2 sticks of this: 9/16"(.5625") x 14"+ 6061 T651 Aluminum Round Bar Cold Drawn Cold Rolled Rod | eBay

2 sticks will do the job.

I cut 3" long pieces and then I mixed up some jb weld and slobbered it on the sticks, and a little in the holes and tapped them in. I let them set overnight.

I used the measurements you gave me from the w5s to lay out the holes. I marked the centers with a punch, and then set up the head on the seat /guide machine at the angle I wanted. My math came out to just under a 6 degree angle. I used a pointed champher bit to center the table on my punch marks. Then switched to an end mill to make the holes. You have to feed it really slowly at first. A bridgeport mill would be the best way to do this, but I don't own one.

I started this because I picked up a set of W2 rockers cheap. They ought to be good enough for an ugly Yeller truck.
