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) ]

Why don't you use the 2.0L heads? Carb manifolds for 2.0L heads are cheap enough. I have a pair I would swap you for 2.0L FI runners if you have extras.
