60cc
i just removed the heads in my 70' Chevy Monte Carlo. its a small block so i had to remove 17 head bolts. big blocks however are differrent. so it depends on the size engine you have.
I would recommend getting a chilton's manual. not to tough of a job, just make sure you have you heads checked.
if it would fit on there it probably wouldn't run the greatest. putting 305 heads on a 265 make the combustion chamber bigger, which causes a loss in compression... i wouldn't do it if i was you
The combustion chamber size of the heads with the casting number 376450 is 60cc. It is possible to install larger valves.
it all depends on the head chamber volume of the 307 heads and the 350 heads that are being replaced. if the 307 heads have a smaller chamber volume then yes, they will bump up compression.
the local shop wanted $1400. DIY cost me about $700 for gasket set and having heads checked.
as you looking the heads front side exhaust entry back side intake entrys so is ease the push rods are different lenghts intake are smaller and exhaust are bigger
i need to know what torque the head bolts down on my 1996 Monte Carlo cause i just got done doing a head gasgets on and i need to also need to now what to torque the rockers thank u for your help The rockers are done with the engine running. Turn till they stop clattering and back off a quarter turn for hydraulic cams. Solid cams will have a lash setting on the cam card. have found that for initial startup lash all the rockers at .020 with the lifter at the base of the cam and this will help start the engine and keep it running while you finish the adjustment
The intake manifold attaches to the heads of the engine and send an air and fuel mixture to the combustion chamber through the intake valves. The intake manifold is usually situated on the top of the motor.
