More CAM ADVICE Please

[BDF]

I got my cam & lifters and drove them & a head/valve gear up to Gary at Rocker Arms Unlimited. He is going to mock up an engine make me some ss roller tip rocker arms.
The pistons are Icon 843s, .010 in the hole.
The cam is single pattern @ 274 adv dur @ .015 lift. It will be @ .540 lift. It is 114 LSA, 110* intake, 118* exhaust.
I don't know the .050 duration numbers yet but it has 'Winfield' lobes with what I understand to be a lot duration at the nose.
