Anyone know if relieving the edge of the fuel bowl has any measurable affect on compression numbers?

Hotrodtractor,
How far back have your bowls been cut?
What does it cost to have the edge removed or if for a stock build, can this be done at home with sanding rolls?
is there any advantage to leaving the lip?
There can be to a point..... maybe not so much in leaving the lip - but there are decent power gains and efficiency to be had by adjusting the bowl shape - having some of the "re-entrant" lip design built in has shown some advantages in combustion chamber turbulence. I have spent a decent amount of time looking at combustion chambers and talking with guys about combustion chambers that I know that the next engine I build for myself will have something drastically different in it.
Are those roller rockers I spy in the background?

They sure are -.
Hey now, thats the first I've even HEARD of rollers for a 7.3, much less SEEN them. Custom one of a kind or...?
Never done 7.3 pistons but i use a fletcher for sharp aluminum edges.Hotrodtractor,
