Default How much flow would I gain if.....

Increasing from stock 5.3 valves to 2.00. I currently run stock size with 5 angle job on them. I'm currently run ported heads with stock valves( don't ask) and am wondering if it would be worth the time? My heads flow 247 @550. Thanks ahead for your time. Kerry.

If your heads are on a 5.3 you probably wouldn't see any worthwhile gains.

The valves are going to get shrouded by the cylinder wall. 5.3 bore is only 3.78 in
