4291460-Standard 429 and 460 cylinder heads are essentially the same on a yearto-year basis. As a result, they are 100- percent interchangable. '68-'71 heads use the cast-iron, rail-type rocker arms and positive-stop studs. Chamber volume is 75.8~~. Valve sizes remained the same at 2.084 inches and 1.653 inches throughout the 4291460's production. Pivotguided, stamped-steel rocker arms replaced the rail rockers in 1972, and the combustion-chamber size was increased to 91.4cc, making the 4291460 a lowcompression emissions engine. In 1974, the 460 combustion chamber was further increased to 96.2~~ as the last significant change to this cylinder head. 429CJ and SCJ-CJ heads produced prior to Nov. 1, '69 and SCJ heads are identical. They have 73.5~~ combustion chambers and 2.245-inch and 1.725-inch intake and exhaust valves. Rocker arms are stampedsteel, pushrod-guided and adjustable, the same as the 351C Boss and HO engines. CJ heads built after Nov. 1, '69 use nonadjustable pushrod-guided rocker arms. Positive-stop rocker-arm studs are used. tion-chamber volume was 89cc and valve Otherwise, they are the same as the sizes were reduced to 2.197 inches and earlier heads. 429 and 460 Police-1971 429 Police 1.653 inches. Pushrod-guided stampedsteel rocker arms and positive-stop studs cylinder heads are essentially the same as are retained. The last Police head, prothe late 429 CJ heads with non-adjustable duced from 1975 on, is identical to the rocker arms. Combustion-chamber sizes standard passenger-car head.It has 96.2~~ were increased to 91.5~~ in 1972 for combustion chambers, 2.084-inch and lower compression, otherwise the '71 and 1.653-inch diameter valves and non- '72 heads are the same.

Assuming all mechanical components are compatible, never interchange cylinder heads without first checking compression ratio. You could end up with an engine that won't run on available gasoline due to excessively high compression or one that performs like a dog because of low compression. Use this chart for reference.
