    Valve springs: If you are hitting valve bounce, new springs will be essential won't it?

    My thought as well, any recommendations?

    I've been looking at some double Iskendarians.

    Isky, piper, kent, schrick or what the cam manuf recommends. If you do some measurements you may find another car has the same sizes

    Higher the better isnt it? Avoiding pre-ignition obviously

    I'm no expert, so treat everything I say with a pinch of salt. In your position I would look at how easily you can gain an atmosphere extra. More comp, same RON generally means less advance in the middle rpm range, as I understand it. Mappable ignition and a rroad with some pinking headphones and a lot of rr time to set it up. In other words, make a decision and give it a try. Then tell us when it turns into a pile of poo, so we can all learn...
