[QUOTE="Hotrodtractor, post: 24318, member: 25"] The bowls pictured are straight cut to the largest diameter of the factory bowl. This cost can vary - but somewhere between $10-30 per piston is what I have seen depending on the level of work your looking for (bowls opened up, radiused, valve reliefs, adjusting the deck height, etc.. all add up). There can be to a point..... maybe not so much in leaving the lip - but there are decent power gains and efficiency to be had by adjusting the bowl shape - having some of the "re-entrant" lip design built in has shown some advantages in combustion chamber turbulence. I have spent a decent amount of time looking at combustion chambers and talking with guys about combustion chambers that I know that the next engine I build for myself will have something drastically different in it.
