This one is definitely a don't. You are correct about the quench, but quench is much improved by reducing the volume under the quench areas by bringing the head closer to the pistons. You are also correct that swirl does not come from squish, but tightening the squish has a number of significant benefits. In no particular order: Intake charge trapped under the quench areas does not burn, and is wasted. Exhaust gases trapped under the squish areas are not completely expelled and dilute the next intake charge. Burn rate is made faster, requiring less ignition advance and allowing higher compression without pinging. The faster burn transfers energy to the pistons more efficiently. Less heat is transfered to the head. All this is quite well documented, going back to Smokey Yunick in the 1970s. It works in Formula One, it works in two-strokes, and it works in old Volvos (it does not work on flathead engines, and does not apply to Hemis). Aaro, Parker, Hueppchen, and I all agree on this and have demonstrated it many times over. Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
