in preparation for porting the intake manifold to match the outlet of the 60 mm throttle body, i've sanded the rocker cover (the new one) and now it shines! more or less. took 3 hours of wet sanding with 600 grit sand paper and this is the outcome

look at the difference! now, the only thing remaining is if i should paint it or buff it?
what do you guys think?
my to do list(board):

it will be filled up with things to do during my 2.5 weeks break. so stay tuned for more putra prepping. hope all goes well by august.
