CNC PORTED ED 'LA' STYLE HEADS

INCL. HEADS W/ 2.08' INT VALVES, SEALS, CNC PORTING

$2540.00

Closed Chamber 65cc (before porting)  #60779 With Stage 3 CNC Porting This is a fully CNC-ported set of new Edelbrock heads for the small block "LA" engines.
Fully CNC'd head and chambers.
This pair of  heads is fully assembled with valves and Edelbrock springs. A spring upgrade may be necessary depending on your cam requirements.
 This level of ported head will support approximately 690+ horsepower in the proper engine.

Flow tests below show results from our custom-built bench.

CNC porting of the heads will increase the overall chamber size. If you need the heads milled to a certain cc or are trying to achieve a specific compression ratio,  let us know and we can quote you a price on milling.
