flycutting heads
« on: May 02, 2010, 05:40:54 PM »
i'm going to put my ported and polished heads (stock valves) on my 1641 (balanced and blueprinted, with an engle 110)

the heads still have the lip on the sealing surface and i want to bump up the compression. how much should i machine off? i'm not running any spacers under the cylinders.


i'm really sick of losing to a stock 280z at the drag strip >:(
