Milled 243 Will there be a problem milling the 243 heads to 57cc.not talking about clearance or anything just milling,will that much effect flow numbers,run hot or anything that could hurt the heads
As long as you stay under .040" on the mill, you should be okay. Flow will be affected somewhat, but no enough to make up for optimizing your compression. Just make sure your manifold aligns.
