360 head trip
[/QUOTE]Well valve jobs is something I dont do and farm out to others.
Typically a 70/45/30 3 angle would work nice, but there are some who use 5 angles.
The top cut some do 'chamber side' would make a nice radius transition from the seat angle to the chamber but requires loweering/sinking the valve job some...[/QUOTE]
The Direct Connection Manual said to use a 70/45/15 degree 3 angle valve job on small block heads. They also say not to sink the valves past what is needed to get a good seat, centered on the valve face. 70 degrees was too much for my seat grinder and would "Bust" stones so I backed off to a 60 degree bottom cut. This worked very good for me, but I had a good teacher. It's nice to see you doing this in stages so people can see what they may be up for, and the benefits derived. Thanks...
