The 5.8 is formally known as the Trinity Engine or 5.8-liter V8 engine, which benefits from cylinder heads with improved coolant flow, Ford GT camshafts, piston-cooling oil jets similar to those found on the 5.0 Coyote, new 5-layer MLS head gaskets, an over-rev function that increases the red line to 7000 rpm for up to 8 seconds (from 6250 rpm ...
This problem did not appear until the engine had over 50,000 miles (80,000 km) on it. By late 1956, many Olds dealers learned about the problem. Compression was up again in 1956 for 230 hp (170 kW) and 340 lb⋅ft (460 N⋅m) in the 88 and 240 hp (180 kW) and 350 lb⋅ft (470 N⋅m) in the Super 88 and 98.
Ford offered a performance head that was a stock part on 1993–1995 Mustang Cobra models and pre-1997 ½ Ford Explorers and Mercury Mountaineers equipped with the 5.0 L engine called the GT-40 head (casting ID F3ZE-AA). In mid-1997, the Explorer and Mountaineer 5.0 L heads were revised and renamed GT40P.

These engines were based on the Hemi engines, using the same blocks and crankshaft parts, but completely different cylinder heads, pushrods, exhaust manifolds and pistons. They were called Polyspheric or Poly engines, because they featured polyspherical-shaped (meaning "more than one sphere") combustion chambers. These were formed by two ...
The standard head seen on an L78 400 Pontiac was the low compression 6x8 head, while the 6x4 head seen on the W72 had hardened valve seats for a higher RPM operating range, improved air flow, and higher compression. These heads can be distinguished from 6x8 heads through a small stamped "4" on the top of the front boss.
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
