can you use a 2L exhaust valve in a 1.8L head? [after machining, of corse (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) ]
i was thinking [ (IMG:http://www.914world.com/bbs2/html/emoticons/smoke.gif) ] of only bumping the exhaust up to 36mm, and leaving the intakes at 41mm? common practice? weird? i have a set of loaded, rebuilt 2L heads; but i want to use the Solex PII 40's Joe Sharp gave me*, so i'm gettin' some 1.8L heads... * [thanks again joe (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/boldblue.gif) ] |

You can also have the 1.8 spark plug holes welded up and relocated to the 2L position. You can also go for smaller diameter spark plugs so that they don't crack in the future.
