clio valver inlets

hi does anyone know how much you can bore the inlets in the head to?

From what I remember there are no real gains to be had by doing this, as they are pretty much spot on with the engine ports

if your talking about valvers, then get a full williams F7R engine. They have a bigger port head, but tbh it'd be a waste of time just running the head on the F7P block.

?

valver and williams ports are near identical...the williams has 32mm inlets, so marginally larger than the F7P.

Theres plenty of gains to be had by fitting larger inlets. Ive sold many of my ported heads using over-size inlets.

Porting and flow rates etc, are a little more complicated than boring it to the biggest size!
