To clarify, that is a kit that Melling offers, it is some gaskets and a cast iron wear plate. Also, use the oil filter adapter off of the 350 if you have room. If you are going to rebuild the 350 before you install it, upgrade to rubber style front and rear main seals. If you have acccess, find a machine shop to drill the oil galley in the block out to 1/2 or 5/8 it will net 10 to 15 more psi of oil pressure with no ther changes. Also run B12B Turbo Buick 3.8 front cam bearing that is grooved on the outside for additional lifter/rocker arm oiling.
By the way Valvoline VR1 Racing Oil has the ZDDP to keep the flat tappet cam alive.
Lots of guys seem happy with Comp Cams 268 for the 350 Buick.
