To make horsepower, you want some heat to be retained in the combustion chamber with no detonation or preignition, which makes aluminum a wonderful selection. Straight ethylene glycol and methanol have been less corrosive than the proprietary items, which contain inhibitors of iron corrosion. The Vortec head drastically outflows their non-Vortec service replacement head and gives a 20-40 hp boost over earlier cast-iron heads.

We’ve gone to great lengths to make improvements over the stock cast iron Vortec cylinder head. The Freedom Series 185cc heads tested Initial in peak horsepower, Initial in average intake-port flow, 1st in average power, and Second in typical horsepower per dollar. Stud girdles made for stock Chevy castings as well as other aftermarket pieces that have normal valve angles will not match properly. Raylar large block Chevy / GMC cylinder heads out flow every single eight.1L cylinder head on the market.

This variety of surface would probably be okay on a cast iron or aluminum cylinder head offered the scratches are not also deep and do not generate leak paths. Too numerous instances guys tend to buy cylinder heads primarily based on higher lift flow numbers that are simply accomplished with big ports and valves, but do not necessarily supply them with the performance they are searching for,” added Feeney. Engines with 1/2” head bolts holes (351-w and 302 CI SVO) need to use ARP #154-3603. These aluminum heads feature 195cc intake runners and 68cc combustion chambers.

Your heads have been washed in a water soluble chemical agitation tank and blown out with higher stress air three to 4 times just before they have been boxed. Precoating the aluminum with lubricant and using lots of coolant should stop clogging. Keeping all moving components inside the block has an advantage for physically large engines in that the camshaft drive gear is tiny and so suffers less from the effects of thermal expansion in the cylinder block. Dart created the Iron Eagle heads for street efficiency, bracket racing, oval track competition, and higher-functionality marine use.
