904 transmission shifting adjustments

Any other thoughts on this stuff guys?

Im using dayco transmssion cooler line, DAYCO® Transmission Oil Cooler/Power Steering Return Line Hose think this stuff will hold up, or do i need to use some copper, aluminum or braided lines?

Another questions i have is how do adjust my valves, i have 587 heads (are those considered 360 heads?) with the 273 adjustable rockers, how do i adjust those or check adjustment? When i first blue printed the engine, i found some excessive wear on the rocker shafts and rock arms on one side, i polished them up to smooth them out, im thinking some of the oil passages were plugged? anyway now i need to check and adjust them. Valve cover gaskets are leaking, so i can address this at the same time, any ideas on the gasket and what is the best installation method.

Any one here updated the rear axles to get a bigger bolt pattern for bigger tires?

I got the hood scoop done, check it out, i bought it off craigslist for 65 bucks. Im getting a k and n x stream airflow top plate so that air will be pushed right in the top of the air cleaner.

What are your guys guess on the horse power? I should be going to the dyno soon, if the winter stays away.

Any ideas on some mufflers that will make it quiet but hold up to the horsepower without taking away horsepower? i was thinking of adding a H pipe too. i have the summit mufflers in it right now, 3", 633230, still to loud

Kern Dog any more ideas, think i should take that accumulator spring out or do you think its probably already gone? Also should i try adjusting line pressure? The shifts are way better now that lever is in the right spot, but i think i have room for improvement.

Thanks for the input
