[QUOTE="Goatrider, post: 707573, member: 13444"] My 258 in my jeep kinda gave up last trip so I'm putting together a low mile 304 from my dads barn that is in good shape, and I have a set of 3196291c amc 360 heads I have from a swap meet. My issue is from what I'm reading, some people (other forums) had issues just bolting these heads on and some people never have a problem, because the valves in the higher cubic inch motors are some much bigger... Does anyone know about doing this swap? Or should I clean up and bolt the original heads back on? The 304 heads are Intake: 1.787 Exhaust: 1.406 With 58.92 cc combustion chamber The 360 heads are Intake: 2.025 Exhaust: 1.68 With 50.6 cc combustion chamber The 360 heads should considerably flow better and create more compression (research came up with 2 numbers for compression with these small cc heads, 9.5 and 10.5) I'm also planning on running all stock internals except a k8600 summit cam and lifter combo (cause it's a budget build) Can spec is 289/300 duration .473/.497 lift With a 112 lobe separation Sent from my iPhone using Tapatalk [/QUOTE]
