If I wasn't shooting for high HP. Then I don't think it would be much of a problem, just concerned about the parts I plan on spending a lot on. But I do see the benefits of having them, this is why I thought I'd ask.
The high HP reason for deleting is because people want extra oil pressure for safety margin, and sometimes a little less windage from the fluid contacting the rotating assembly. Well, sometimes it's because people remove balance shafts or something like that and now have enough engine vibration to fatigue and break off the squirters from the block bosses....
If your pistons are hot enough to warp with oil (even if your engine somehow became very hot before the squirters started flowing...?), your engine is going to die a horrible melty death very soon. There will always be a temperature gradient from one side of the piston crown to the other, especially if there is a squirter installed, and the oil continuously cools the piston (engines make heat continuously, and the squirters flow oil continuously too...) which is one of the reasons that squirters are useful. Cooler pistons mean more power generation (less detonation, more ignition advance, etc.), and a happier engine.
That's why NASCAR and Formula1 say your logic is flawed, they run multiple squirters per cylinder and rely on squirters to make big power and keep the engine alive.
If F1 made frying pans, I wonder if they would be made of titanium or AlSiC..? Maybe carbon/carbon for grilling. Maybe beryllium before the ban..
