Edelbrock Performer RPM 62055 is a performance aluminum cylinder head for Small-Block Ford builds that need more airflow than OEM-style designs. It is part of Edelbrock’s Performer RPM direction, aimed at meaningful engine performance improvement rather than routine replacement or restoration-only use.

205 cc intake ports, 62 cc exhaust runners, 60 cc combustion chambers, aluminum construction, and .650 inch maximum valve spring lift. Those details make it relevant for builders planning a stronger small-block combination where airflow capacity, chamber sizing, and valvetrain range are important before final engine assembly. It also keeps the purchase focused on a matched head configuration instead of piecing together separate core components.

This product is listed for racing or pre-emissions applications only. Confirm emissions legality in your state before purchase.

Edelbrock Performer RPM 60215 is a performance aluminum cylinder head for Gen I Small-Block Chevrolet engines using a roller camshaft. It is built as a serious airflow and combustion upgrade, not a stock-style repair part, with a 210 cc intake port volume focused on stronger breathing for performance engine combinations.

Aluminum construction, 210 cc intake runners, 75 cc exhaust runners, 64 cc combustion chambers, 1.55 inch valve spring diameter, and .65 inch maximum valve spring lift. That gives builders a more capable head package for combinations where airflow, valvetrain compatibility, and proven Edelbrock performance architecture matter.

Edelbrock Performer RPM 61039 is a performance aluminum cylinder head for Small-Block Oldsmobile builds using a flat tappet camshaft. It is not a stock replacement part; it is a performance-focused head package built to improve airflow capacity while preserving the Oldsmobile-specific architecture needed for the right engine combination.

Aluminum construction, 200 cc intake runners, 130 cc exhaust runners, 68 cc combustion chambers, and factory 6-degree valve angle geometry. The head is aimed at builders who want a stronger top-end foundation for a flat tappet cam setup without moving into a custom-fabricated cylinder head solution.

Edelbrock Performer RPM 61035 is a performance aluminum cylinder head built for Small-Block Oldsmobile engines using a hydraulic roller camshaft. It gives the build a stronger airflow foundation than stock-style hardware, with Edelbrock’s Performer RPM architecture focused on street and strip performance rather than basic repair replacement.

Aluminum construction, 200 cc intake runners, 130 cc exhaust runners, 68 cc combustion chambers, and factory 6-degree valve angle geometry. That combination is aimed at builders who need a complete head package with real performance intent and known Edelbrock engineering behind it. It also keeps the purchase focused on a matched head configuration instead of piecing together separate core components.
