Phenolic Spacer...Bad for Performance?

[blake buckman]

remember the shorter your runners better top end power, longer better low end breathing. It does somewhat help your air charge temp. to reduce, due to less metal to metal contact with HEAT soaked Lower intake. personally I use a half inch port matched cobra intake with no clearence problems. I strongly advise port matching spacer to BOTH UPPER AND LOWER. Since they don't always line up when bolted together. There is an easy trick on saving gaskets w/ spacers. Buy some brush on RED LIQUID GASKET and glue your gaskets to the spacer and they will not move upon installation!! I have used the same gaskets several times/
