Proving that it can be done opens a lot of possibilities. For me though, I have to wonder how much valve is overkill considering the tiny npi exhaust valve is now closer to the bore. Or is it not overkill? Most ptv clearance issues are on the intake side, how much does that situation change with larger, offset valves? I'm interested to see how the flow changes with the offset, even with stock valves. When does the offset/ larger intake become restricted by the changes in moving the exhaust side ?</p></blockquote><p></p>
