With our engines all comes to microns which is impossible to get produced out of the machines. Even after grinding the sleeves and pistons still a matching of piston and sleeve is done so after seveal processes it is unclear which parts you have from which timeline of the production.
As mentioned by me, the goldhead could have better mached parts for an optimised performance.
roelf lets break that down cause that don't make sense first off os is not making f1 custom engines for each client they are a factory that mass produces these motors they cut 100 blocks 100 sleeves and 100 pistons and so on and on the factory line as they some out there is a cute little Mexican guy that most likely don't have according to trump his citizenship and he assembles the motors as they are made. second u want to say the gold head is better matched then the black head so how can that be does the guy who assembles the gold head have better reading glasses then the guy with the black head u see what I'm getting at the motors are just assembled and the heads slapped on so there no way they assemble one unit and say oh this is for the gold head. further more I really hope u don't believe that these mass producing companies are sitting there matching these units !! lol
