Block 1968-69 Hurst OLDS D Heads

⭕ I never thought id sell them.. but here it goes.. Very RARE and VERY valuable 1969 W30 / 1968-69 Hurst OLDS D Heads.. these are the rarest heads Oldsmobile ever made.. pure gold to the olds enthusiast.

*D 400370 69.75cc 2.072 1.625 68-69 400/455s, with W-30 or H/O [except A/C 68 H/Os- see C]. Large valves, 2.072 and 1.625. Shallow spring seats. No hard exhaust seats. Smaller combustion chambers than other BB heads, possibly due to the small bore of the G-block 400 motors. Rumored that the 68 versions had both center exhaust ports connected to the crossover, whereas an improved later version as used in 1969 had one port blocked off from the intake heat crossover port for better power. Improved port configuration for better flow-. Very rare and valuable.
