Dump the 009 and get the Mallory, you don't need the one with vac advance so you will save a few $$. These distributors are really great and tuneable to the advance curve your engine needs. It always amazes me when VW people just slap in an 009 distributor and expect it to run correctly. V8 builders have known for years that every engine requires it's own advance curve for optimal operation. The Mallory is more $$ than a 009 but you will never regret it. I run a stock Mallory on my beater trash bug with an unknown engine and it made a world of difference over an 009 and an old school 019! I bought that distributor for my 2.0l type 4 and just slapped it in my trash bug after taking my 019 out in disgust, now I need to buy another for my type 4!

I know you can get the detonation to stop with the correct advance curve.
