Nice work you have done & fast!

Did you get guides installed or they were good?

From the pics, it does not look like the valves were back cut?
Hard to see for sure if there are two angle cuts?

Not sure if it just has a 45 degree cut.
Having a wide margin for the seat & no back cut on the valves can hurt airflow.

But, having a large 45 degree seat will make the valve job last longer.

Are you going to make a sheet metal intake manifold for this engine or for a turbo engine?

I'll say you have it running in a couple days, you work fast.

Nice work again!
