Dart 205's w/TR224, Quench and DCR ? I've got Dart 205's on the way from Summit, suprisingly they got them out quick, I thought I would have to wait. The heads are 62cc chambers. If I use an .041 head gasket my static compresion will be around 11.1/1, and the quench will be .033. The thing that bothers me is the DCR will be around 8.7/1. I read that you don't want to go above 8.5. I can use an .054 gasket and get the DCR to or just below 8.5 but that pushes the quench up above .050, also not good. I'm thinking go for the .033 quench and 8.7 DCR won't be a problem. Am I wrong? Also can you use a 4.135 dia. head gasket on a stock bore motor 3.898? Thanks.

Your 224 cam may have +4 degrees advance ground in already. Will retarding your 224 cam -4 degrees reduce DCR?

Retarding cam raises power band very very slightly. You can do this simply by installing camshaft degree bushings.http://store.summitracing.com/defaul...=egnsearch.asp

It sounds like you have a pretty good street combination. I will also be sticking with my 224 cam in sig. Can you post pictures of your heads? Intake ports, combustion chambers, valve pockets, etc
