Default 455HO build up - lets hear it

Ok so doing a 455HO which presently is still stock bore and stock virgin heads. Just want a fun street motor. Have all the power I need in other cars.

Wish to go roller cam though and will not be touching the 108cc 7F6 heads other than new valves and rocker arms etc. Compression should stay under 9:1 with flat top pistons.

Keeping stock crank but getting forged Molnar stock length Pontiac rods.

What roller cam specs will work best? Been leaning towards around a 230/236 at .050 with a 112LSA.

What roller rockers would you recommend?

Does the stock intake and heat shroud assembly work with the tomahawk style valley pan needed to clear roller lifters?

Stock exhaust manifolds.

Lets hear it.

Thanks.
