Anyone know where I can find the aluminum valve spring retainer #330586 that fits valve spring 330585. I can't seem to find any aluminum valve spring retainers.

Thanks for any help

 

You going to use this on a street motor??

 

The reason why you can't find them anymore is because they were a bad product that failed within days, sending aluminum shavings into the engine oil.

 

I'm just joking no way on the planet I would use an aluminum retainer
even when I was younger when chevy sold them over the counter.
Those two part numbers are legitimate chevy part numbers from the fith edition Chevy power parts book. Chevy out to be shot for putting out junk like this for sale.

 

I ordered mine from www.sdpc2000.com I guess its www.sdparts.com now.

 

I've worn out titanium retainers in just a couple of years. I was wondering if aluminum might last on some low spring weight h-flat cam or something.
