TX WTB early Corvette rocker covers,road draft tube, ram horn manifolds, aluminum intake

[WIDESIDE72]

I recently picked up a rebuilt 283 for my 57 NAPCO. It currently has the stock stamped steel valve covers, a cast iron 2 barrel intake and carb. No exhaust manifolds. I am also missing the road draft tube the bolts to the block by the distributor. If anyone has a reasonably priced set of “staggered” corvette rocker covers, stock type “rams horn” exhaust manifolds and period style aluminum intake like an Edelbrock C3B/ C3BX intake with the oil filler tube provision, please advise cost and total price shipped to Leander Tx 78641.
