you can either scale it mechanically by allowing for a larger sample volume than OEM, or you can scale it with a frequency reduction

heads are not really any better, just a new series of molds went online so your less likely to get a reworked mold head that has massive core shift, remember those head molds for the casting sand were in use from 93+ (first SII 3800 being in the 94 model year) so by 00+ they were pretty beatup.
an early mold 7 is a great head, a 99/00 mold 7 has nearly 1/4" core shift on the one end cylinder. the valves weren't better, just cheaper, same with the rods..... thanks bean counters.

pistons yeah, better anodizing and the skirt coating (that wears away quickly anyways), the rods were just cheaper to make/machine. Powdered metal forging is not stronger than cast, just more brittle.

its the only way that the fractured cap technology works...is by engineering a brittle rod that's barely a step above sintered metal construction.

ive seen thrown rod L36's where you have the cap/rod twisted into damn near a pretzel with the block/bore/pan/skirt thoroughly ****ed....you look at a thrown rod L26 and you find the rod in 8-400 pieces and barely a mark on the block...

ive seen this enough times that I don't like the PM stuff....at all

id rather find the L67/32 (steel pan L32's) that have the L67 cast rods with the L32 pistons/front cover
