# Edelbrock SB Oldsmobile Performer RPM Cylinder Heads for Hydraulic Roller Cam Intended for installation on 1965-1976 Small-Block Oldsmobile 350-403 c.i. engines equipped with a hydraulic roller camshaft, these 356-T6 aluminum casting cylinder heads (#61035) are a modern refinement to our #6051 heads, except they can accommodate a factory-style mechanical fuel pump. A smaller 68 cc combustion chamber achieves a more appropriate small block compression ratio compared to our PN 61025/61029’s larger 77 cc chamber, which yields a lower compression ratio than most engine builders desire on a small block engine. These heads require a 3.9375” minimum bore and feature a modern chamber design with optimized spark plug positioning. Maximum airflow is achieved through the factory 6-degree valve angle using high-flow 200 cc intake and 130 cc exhaust port volumes, along with 2.072” intake and 1.680” exhaust valve sizes in their O.E. positions. A finished deck thickness with added material above the intake port and pre-counterbored head-bolt holes for .5” diameter studs provide extra clamping force in key areas. A stud-and-guide plate valvetrain system (as opposed to the O.E. pedestal type) provides a solid foundation for the beefier diameter pushrods, and Helicoil inserts in the exhaust and rocker stud holes keep bolts secured. However, there are no provisions for a heat crossover.Although these heads will fit on Big-Block Oldsmobile engines, the 68-cc combustion chamber size is not ideal for a big-block application as it will raise compression. See PN61025 and PN61029 for big-block specific cylinder heads. - Retains compatibility with OEM and popular aftermarket manifolds and Headers - Maximum compatibility with OEM and aftermarket components - Allows the use of an "OEM" style mechanical fuel pump - Mechanical Fuel Pump Clearance Cutout - Factory 6-degree valve angle - OEM Port Locations This Part Fits: Year Make Model Submodel 1975 Buick Apollo Base 1975 Buick Apollo SR 1975-1976 Buick Century Base 1975-1977 Buick Century Custom 1976 Buick Century Indianapolis 500 Pace Car 1975 Buick Century Luxus 1977-1979 Buick Electra 225 1977-1979 Buick Electra Limited 1978-1979 Buick Electra Park Avenue 1977-1979 Buick Estate Wagon Base 1975,1977-1978 Buick LeSabre Base 1975-1978 Buick LeSabre Custom 1977 Buick LeSabre Custom Sport 1975-1976 Buick Regal Base 1976 Buick Regal SR 1977-1978 Buick Riviera Base 1978 Buick Riviera LXXV Anniversary Edition 1975-1976 Buick Skylark Base 1976 Buick Skylark S 1975-1976 Buick Skylark SR 1976 Cadillac Seville Base 1975 Chevrolet Bel Air Base 1975 Chevrolet Camaro Base 1975 Chevrolet Camaro LT 1975 Chevrolet Camaro RS 1975 Chevrolet Caprice Classic 1975 Chevrolet Caprice Classic Sport 1975 Chevrolet El Camino Base 1975 Chevrolet El Camino Classic 1975 Chevrolet Impala Base 1975 Chevrolet Impala Custom 1975 Chevrolet Impala Sport 1975 Chevrolet Monte Carlo S 1975 Chevrolet Nova Base 1975 Chevrolet Nova Custom 1975 Chevrolet Nova LN 1975 GMC Sprint Base 1975 GMC Sprint Classic 1975 GMC Sprint High Sierra 1975 GMC Sprint SP 1977-1979 Oldsmobile 98 Luxury 1977-1979 Oldsmobile 98 Regency 1977-1979 Oldsmobile Custom Cruiser Base 1975 Oldsmobile Cutlass 442 1968-1975 Oldsmobile Cutlass Base 1977 Oldsmobile Cutlass Colonnade 1976-1977 Oldsmobile Cutlass Colonnade S 1972 Oldsmobile Cutlass Cruiser 1968,1971-1977 Oldsmobile Cutlass S 1976-1977 Oldsmobile Cutlass Vista Cruiser 1975-1977 Oldsmobile Cutlass Salon Base 1968-1977 Oldsmobile Cutlass Supreme Base 1977 Oldsmobile Cutlass Supreme Brougham 1976-1977 Oldsmobile Cutlass Supreme Colonnade 1974-1975 Oldsmobile Cutlass Supreme Cruiser 1975 Oldsmobile Cutlass Supreme Hurst 1976 Oldsmobile Cutlass Tiara Base 1968 Oldsmobile Delmont 88 Base 1968-1979 Oldsmobile Delta 88 Base 1968 Oldsmobile Delta 88 Custom 1972-1979 Oldsmobile Delta 88 Royale 1968-1972 Oldsmobile F85 Base 1973-1976 Oldsmobile Omega Base 1976 Oldsmobile Omega Brougham 1976 Oldsmobile Omega F85 1975 Oldsmobile Omega Salon 1976 Oldsmobile Omega SX 1977-1978 Oldsmobile Toronado Brougham 1977 Oldsmobile Toronado XS 1977-1978 Oldsmobile Toronado XSR 1968-1975 Oldsmobile Vista Cruiser Base 1977-1979 Pontiac Bonneville Base 1977-1979 Pontiac Bonneville Brougham 1978-1979 Pontiac Bonneville Safari 1977-1978 Pontiac Catalina Base 1977-1979 Pontiac Catalina Safari 1976-1977 Pontiac Firebird Base 1976 Pontiac Firebird Esprit 1976-1979 Pontiac Firebird Formula 1977-1979 Pontiac Firebird Trans Am 1975 Pontiac Grand Am Base 1975-1977 Pontiac Grand LeMans Base 1977 Pontiac Grand LeMans Safari 1976-1977 Pontiac Grand Prix Base 1977 Pontiac Grand Prix LJ 1977 Pontiac Grand Prix SJ 1975-1977 Pontiac LeMans Base 1977 Pontiac LeMans Safari 1975-1977 Pontiac LeMans Sport 1975-1976 Pontiac Ventura Base 1975 Pontiac Ventura Custom 1975 Pontiac Ventura S 1975-1976 Pontiac Ventura SJ ## Details - **Price:** 1745.16 CAD - **Vendor:** Edelbrock - **Type:** Heads ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 1745.16 CAD | In stock | ## Images - Photo - Primary - Photo - Mounted - Photo - Close Up - Photo - lifestyle view - User 3 - User 6 - User 7 - User 5 - User 9 - Photo - in package --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/edelbrock-sb-oldsmobile-performer-rpm-cylinder-heads-for-hydraulic-roller-cam) > Updated: 2026-06-27
