The chambers are 60cc. The heads are from 77-78 307 engine.
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.
Engine heads are constructed of iron or aluminum.
if you make the combustion chamber smaller for example by shaving the heads when the sparkplugs ignites , the piston will get pushed down harder there for make your engine go faster .In short, reducing the combustion chamber size increases the combustion ratio which increasing the explosive force of the air fuel mixture when it burns. The negative side of this is fuel with a higher octane rating will have to be used to run the engine.
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.
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
the local shop wanted $1400. DIY cost me about $700 for gasket set and having heads checked.
58.cc low torque swirl chamber head
There are two cylinder heads on a V6 3.1L engine.
On top of the driver and passenger silly! Just kidding. The heads are the block of metal bolted on top of the engine and contain the top of the combustion chambers. They may or may not also carry the intake and exhaust valves. Many aircraft engines and some racing engines have no heads, instead they have "pots" covering the piston and combustion chamber as one piece.
piston ride up/down in cylinders in the block - the heads are attached to the block. They seal the compression chamber closed, and house/hold the spark plugs, valves, cam shafts (in OHC/overhead cam engines) and complete the water jacket around the engine. Coolant/water flows through the block and heads - why you lose water when you warp a head gasket, water is going into the compression chamber. When you have an OHV/overhead valve engine, on top of the head(s) is/are the valve covers.
Should be 74cc
It would appear to be a 1974- 1980 because the block # comes up as 69-80 on the year range and the heads come up as 74-80. These Heads have a decent valve size (1.94/1.50 76cc Chamber) but are smog style heads and crack easy. Be carefull
Nothing needs to be done to make them fit. The only problem you would have is the compression of the engine. Anything larger than a 64cc combustion chamber will lower your compression quite a bit. Do some research and find the small chamber heads or look into having a set milled to spec.

It is not supposed to be an interference motor, HOWEVER at high RPMs the connecting rods may stretch enough that it BECOMES an interference engine, causing some major problems if you break the timing belt or chain at high speeds of rotation. The clearance is very small on a factory engine. If the heads have been decked or the pistons are not stock it may be intereference.
Depends on the heads. The size is different for the exhaust valve and the intake valve, and different engines have different size valves. The valves are mechanical devices in the engine heads that open and close. The intake valve opens to let the air/gas mixture into the combustion chamber,. Both valves close the combustion chamber during the compression stroke, and the exhaust valve opens to let the burnt gas out during the exhaust stroke.
No, they are in the engine block, not in the heads. Freeze plugs are a misnomer. They are actually casting plugs.
