That looks soooo much better, not perfect, but I'd run it as I have seen much worse run without a problem. Pattern may be a little to the outside in 2 pics, but the dark blue line at the edge almost looks like the dykem was still wet maybe. Have you checked to make sure the lash caps are bottoming out on the valve end and not the keepers? Clay

Pattern looks a little wide, but with the HR that may be the lifter. I am sure it will run fine that way.

Take the lash caps off.
You will be in the middle of the valve with less arch front to back.

Try it.

Well I did what I should of done when this happened . I took the heads off, took them to a machine shop. I did this when I realized that the exhaust valves are shorter than the intake. (keeper groove to top) Also that the Pass side had .015 less valve spring spacers than the Driver side. The machine shop that I have been talking to said that it would be a good idea to check everything before reassembly.
Apparently this is not the first engine that this guy has screwed up.

Oh Ya, He's also going to gasket match my intake.

Got my motor back together. It ended up needing longer intake valves, a hole set of pushrods, retainers, keepers, etc. Everything is all good now. Thanks for all the help guys.


P.S. don't let Steve Pait build you a motor.

It is too bad when you have to check everything. You shouldn't. I am glad you found it as everyone said before the carnage.

Leaning is a good thing!
