Most aftermarket modifications are pretty similar from people like Murnan, Rody and Ielasi. Some porting, crank timing and increased flow efficiency. Some are done by hand and others have CNC operations that increase productivity and lower cost for modified engines. The newer O.S. 2104 engines already have many modified features found in aftermarket engines. Murnan is US based so there is that factor to consider as well. Wallace Motorsports is the primary importer for Ielasi and typically have stock on hand once the initial release back orders have been fulfilled. If you are looking for a deal, look for versions from the last few years as they are typically very similar to the new flavors at a reduced price.

With OS from several brands I do see 2 types of crankshafts and basically the same timings on all sleeves (maybe 1 degree more or less). I do not know it all but to e it looks like there is not much or even no afterwork done. Also with all the piston issues on all 9 port OS based engines I do not believe "other" brands have different pistons.
Yes, the only modifiers like RBmods, EWmods, MAG, Murnan, DAP etc are the persons who do plenty af afterwork although I have never had such work in my hands. I do believe many people are very sensitive for the visual work and the "modified" text on the head. and willing to pay a lot for it
