|Jim Rockford||any head larger than 58cc will be useless on a 305. just stick with a good set of tpi 305 heads and you will be fine.|

Yes i have them. There yours if you want to pick them up. If you can figure out how to sent iron heads pm me with ideas.
Had to find the thread again. Not cracked and stored inside.

|allansmith859||Ok thanks for the input. Just curious. Im not doing this cause I dont want to waist these heads on a 305 but how would the 305 react to vortec heads (906) and that cam I listed above. Both heads are 64 cc but of course the 906's flow alot better. Would it be worth doing that. I have two pairs of vortecs but also have two 350 blocks I am putting them on and experimenting with the two. Curious how they would do on a 305 with that cam. Nothing else.|

|spinn||The 305 and like engines are non interference fit. It would take gross amounts of lift and a catastrophic rotational event for the piston to touch the valve.|

|allansmith859||What if I ported those heads and put the cam in the 305. Do you all think that it would be ok for a daily driver. Also I have flat top pistons. Do I need to worry about a valve hitting the piston|

|spinn||THat 420/442 cam is one of the best designs to replace the stock cam. It gives you more power and torque while sacrificing nothing. I have used it many times. It makes a nice driver.|

|allansmith859||Is it because to much compression. Is there any thing I can do to help it perform better. I have a jegs cam shaft. Lift: .420"/.442 Adv. Duration: 262°/272° RPM Range: 1500-4000 sittin in the basement. Would that help it.|

|E.Furgal||it'll run.. but you'll be happer with 305 heads..|
|11-08-2012 12:15 PM|
|allansmith859||So you are saying I cant use these heads for a stock 305 engine that has normal power.|
|11-07-2012 09:08 PM|
|spinn||You want a set of 305 58cc 1.84/1.50 valves 1985 heads that hold water? If i can find them Pm me. You pay shipping.|

Corvette heads are sought after you can sell them and buy a rebuilt set of 305 heads.
083 are 64cc heads normally hot 305's have 58cc heads. if its less compression its going to fall short on power for sure. But i am not much info on 305 engines i just toss then out of the way for something larger. But they can make some good power if done up right.
You may be able to find 58cc heads pretty cheap. They have small bore so many ppl over look them. I have used the heads before on larger engines to gain compression. But not a good choice for any major power upgrade. But will make a nice little street motor.

|allansmith859||How do I do a leak down test??? What about puttin these heads on this engine if everythings good?? (14101083)|

|allansmith859||The cylinder walls look great. There is a very little amount of surface rust that has appeard in two of the cylinders at the very top but I can clean that off. There is no lip at all they look very good. If I put these cylinder heads on this block which is bored .060 over with flat top pistons (head # 14101083). Would it be a good little street motor depending on cam choice and other applications??|
