You will only need like about a ¾” – 1” long piece of pipe for each valve cover. Remove the valve covers, and weld this pipe to the upper – flywheel end – outside corner of each valve cover, and then drill out the inside of the pipes diameter all the way thru the valve cover. Now run new hoses from the valve cover pipes to the air cleaner and you are done! The only downside is this results in your valve covers to now be right and left side specific – but that is NDB. Having the ports on the upper front corners of each valve cover provides for easy access to run new hoses up to the air cleaner.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Dave Pallo<o:p></o:p></p><p class=MsoNormal>'72 Square ~ Elwood<o:p></o:p></p><p class=MsoNormal>Fairport, NY<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
