DynaSpark Opti, is this a good Opti?
 

Ok, I'm going to replace my Opti during my engine rebuild and was looking at the Opti from DynaSpark. I know that it is a little pricey but, where the parts inside are replaceable I thought that that sounds great. I also am wondering with this new opti, would I have to cut off the dowel for my new cam. I have 93 Z and I believe that the dowel needs to be a little shorter. I was hoping with this new opti that I wouldn't have to cut the dowel pin. Any info would be greatly appreciated. Thanks in advance.

The Dynaspark right now is only the vented version. I heard they were working on the non-vented version, but I don't know where in the development they are. I bought a Dynaspark and thought it was worth the extra for what they've put into it. Others don't. Personal decision.
