wow dude,you have one heck of a combo.personally I would use them heads as weight in the back of my truck in the winter,and they do not have 2.02/1.60 valves.put yourself some decent 350 heads back on there a set of headers,and you'll be fine Answer Too much intake??You've most likely chosen an intake that performs at a higher RPM range than what the engine is operating in.And no,STOCK 305 HEADS DO NOT HAVE 2.02 INTAKE VALVES!(unless they have been machined for 2.02 valves).If you do have stock 305 heads on your 350,they are most likely 1.75/1.60 valves.You are starving a performance engine with intake valves that small.Your 650 CFM carb's perfect,just swap the heads.
Intake valves are in the cylinder heads.
yes there are 8 intake valves and 8 exhaust valves in the set of heads
Trace the runners. You can see the exhaust runners leading to the exhaust valves, and the intake runners leading to the intake valves.
Mounted in the heads.
I have the same heads and from the info I found they 76cc heads with 1.72 intake valves
In the cylinder heads.
The 5.7 heads will work if they have the smaller 184 intake valves . Or you will have to bore the block over to get the 194 ,200,or 202 intake valves to fit into the cylinder if not it will lock it up when the valve opens and hits the edge of the block
they could have either 1.94 intake 1.50 exhaust or 2.02 intake 1.60 exhaust
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.
You need to get a Casting # book and look up which heads you have.
That's an easy one. Take the rocker box's, (valve covers) off. The valves that line up with the intake runners, are intakes, and the ones that line up with the exhaust, are exhaust. If the heads are off, always the larger valve, is intake.
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.
