Oversized Valves, N/A Good or Bad?

[Blev]

I was wondering if oversized valves on NON aspirated applications will actually hinder performance. Anyone have some imput on this? Tim?

Thanks

I would think bigger valves would not do much since the valves are already shrouded at there stock size. Now if you have a BB and a P&P head you might see some gain because of the combustion chamber being more accusable and the heads flowing better.

The heads are the Steen Racing Stage 2 heads. I just wasn't sure if it's a waste considering I don't plan on a power adder later.
