Once you get them set to the stock clearance cold, they won't change much and you will get the best performance. .019 and .021" are correct stock ga ps for your engine, but some enthusiasts close them up by .001". As valves wear they tend to stretch their stems before breaking, so it's a good idea to check the gap every 10,000 miles or so and reset, if desired. If the valves have stretched considerably, then they must be replaced.

Personally I'd leave them. Too large a clearance is better than not enough, it's just that you are not getting optimal valve opening. Doubtful you would ever know it though, unless it's a race car. You could also try a different set of feelers. Beatle Oz - -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Eric Sent: Tuesday, 6 December 2011 3:59 PM To: [email protected] Subject: [alfa] 2 liter question I'm installing used Euro carbureted cams on my now-carbureted 76 Spider's engine. According to my documentation* the intake clearances should be around .19 and the exhaust should be around .21. EVERY intake clearance is within tolerance varying between .185 and .195. And EVERY exhaust clearance is outside of tolerance varying between .22 and .23. Do I need to go through massive shim gyrations? Or am I OK? - - Eric Hambleton, Marietta, GA (probably one of the last people in the Digest) Current stable: 1976 Spider - 1991 164b - 1984 Coupe De Ville - 2009 RX8 R3 * The owners manual from a 1974 GTV.

This is good news in that I don't have a big shim kit lying around. I am amazed at how well made these cams must be! I when I put on these replacements after removing the FI type cams, I expected a great deal of variation but there is virtually none. Especially amazed as the 70s were a really bad time for car making for every company. Now I can move on to the rest of the projects...two synchros, transmission seals, diff pinion seal, transmission mount, springs and shocks for the rear, completion of the carb conversion, and many others. I hope to have the car on the road this spring. - - Eric H., Marietta, GA (waiting for that free Berlina that everyone else received) ------------------------------ Date: Tue, 6 Dec 2011 14:29:12 -0800 From: Brian Shorey <[email protected]> Subject: Re: [alfa] 2 liter question It's hard to tell.
