Proportioning valve Question

[bburginger]

A couple questions on what to do on my 62 Impala Build. I'm running Wilwood 14" disk w/ 6 Piston Calipers up Front and the 12.19 Disk and 4 piston Calipers in the Rear. Running the Hydratech Hydroboost w/ will wood Master Cyl 1.12 Bore. My question is what I should run for as far as the proportioning valve? Also another question as far as brake lines can I run just a single flare / AN fittings or should it be the double flare type? Any help or suggestions would be appreciated.
