EngineQuest is taking the marine market by storm with its new Vortec Hybrid head with a heat riser. This newly designed cast iron marine and stock replacement head will work on any small block Chevy application and is the only head of its kind on the market.
“Since a major part of the marine market uses automotive-based engines, our new Vortec Hybrid head provides machine shops and engine rebuilders with an affordable alternative for rebuilding these engines to get increased airflow and horsepower,” said Mark Moore, national sales director, AAEQ.
This cylinder head is based on the EQ Vortec cylinder head that was featured in the popular “Budget Sledgehammer” build in Popular Hot Rodding magazine which produced 447 HP for under $3,500.
EQ Part #CH350G features ’87-’95 intake bolt pattern with center bolt valve cover mounting holes. EQ Part #CH350H is available in the ’69-’85 intake bolt pattern with perimeter valve cover mounting holes. Both heads feature 64cc combustion chambers, 176cc intake runners capable of excellent flow and velocity, standard 1.94 in. diameter intake valves and 1.50 in. exhaust valves. The intake port opening for the EQ CH350G/H is designed like the 68-95 intake ports to provide easier port and gasket matching.
The Vortec Hybrid heads are Australian manufactured and feature a thicker .4375 deck for greater strength, and hardened DuraBond exhaust seats for improved durability. Both the CH350G and H should be used in pairs when replacing OE heads (083, 191, 193, 217 and 810 castings) and are available bare or assembled. To ensure the highest quality, EQ conducts a 25-point quality inspection on every new cylinder head shipped.
