Edelbrock Chevy LS Series Pro-Port Raw Cylinder Heads

Product images may differ from actual product appearance.

The Foundation for an LS Powerhouse!

These unported versions of race-winning Edelbrock Victor Series CNC heads are designed specifically for the professional cylinder head porter and engine builder.

Like all other Edelbrock Cylinder heads, Pro-Port cylinder heads are also cast in the USA at the state-of-the-art Edelbrock Foundry with extra-thick walls to allow for custom CNC porting. In most cases, seats and manganese-bronze valve guides are included, but not installed. Made In The USA!


Please note: These heads can not be used without professional head preparation.


LS1 Gen III Chevy
LS1 PRO-PORT RAW (15° VALVE ANGLE)
A bare, unported version of the our popular head that fits 1997 & later GM Gen III small-block engines from 4.8L to 6.0L.



Victor Jr. LS Pro-Port Raw
FOR GM GEN III & IV SERIES LS3, LS7, and LSX ENGINES
These heads provide head porters with the extra material needed in the ports and combustion chamber for greater flexibility when developing CNC port programs, allowing engine builders to take full advantage of GM's LS series potential. Both LS3 and LS7 versions retain the stock valve location, valve angle, intake flange and accessory bolts locations. They feature a 5/8'' deck and come with seats and guides installed. LS3 Pro-Port heads are 3/4'' taller than stock and have raised spring pads requiring longer valves. Victor Jr. LS3 Pro-Port cylinder head p/n 350-77339 and Victor Jr. LS7 Pro-Port cylinder head p/n 350-77369 are machined to work with standard GM LS blocks. Victor Jr. LS3 Pro-Port p/n 350-77349 and Victor Jr. LS7 Pro-Port cylinder head p/n 350-77379 have the extra head bolt provisions required for use with GM LSX blocks.



LS-R Pro-Port Raw
FOR GM GEN III & IV LS SERIES ENGINES
This head is designed to maximize the potential of GM's race oriented LSX block. It is also compatible with all previous versions of the engine. The true canted valve design offers the utmost in port flow and combustion efficiency possible with a two valve design. The head uses the GM SB2 valve cover footprint required by the added width of the canted valve layout. The stock exhaust bolt pattern is retained. Like all Edelbrock Pro-Port Raw heads, they will require professional preparation, including CNC porting to the port design of choice. Valve guides are included but not installed. This head has been HIP processed to increase density and provide the heads with extreme durability.



HIP Process HIGH-TECH PROCESS DELIVERS STRONGER CASTINGS
Heads are available with a technique called Hot Isostatic Pressing (HIP). This aerospace process takes raw castings up to 900° F in a pressurized chamber (up to 30,000 psi) and compresses the casting. The results: an incredibly strong, super dense sand casting that has three times the fatigue life and nearly the consistency of billet aluminum.
