Edelbrock Performer Heads

[Warren]

Alloy nice shape has 2.02 intake valves very nice shape less than 5000 miles.

I am thinking of building a 289 5 bolt to 302 and staying mild mannered, these are best suited for a 331 or 347 build according to my guru motor building member pals.

Delivery meet up possible between L.A, S.D, O.C. S.B.D, counties.

Port/runner size

Port/runner/ valve size is commensurate with volumetric flow. The "bigger" the heads the more flow required to make them efficient. So, high RPM's and a high RPM cam are usually where you will appreciate the "big" heads...... Disclaimer: I am not an engineer but do recall a great article about Ford big block flow in 428 NASCAR heads.
