Hey guys i'm looking for some advice on heads for a small block. I'm putting a 360 in my scamp come spring and am wondering about these heads. They are casting # 4027596. I did a little reaserch and from what i was able to find they are hp. 360 heads, came on cop cars, trucks vans etc. Is that correct? I'm a young guy (17) and am looking to get all i can out of this motor but money is super tight. I've been working on a trade for my /6 stuff to a guy and he had these heads he wanted to trade. I know that j heads are really the best thing to get a hold of but really i don't have the money that most people want for them. I guess what i'm asking is are these heads worth doing anything with? I'd love to try and get a nice port and polish on them and bigger valves, somewhere in the area of 2.02/1.60's, you guys know the deal. Let me know what you think. Thanks in advance!!

After listening to YOUR questions and intended purpose, I would recommend you use the 596 heads. They have hardened exhaust seats, the large ports, 1.88 intake valves, and 1.60 exhaust valves. In my humble opinion, for a street car / every day driver, I'd want cast iron heads and a Carb with an automatic choke. 340 or 360 4 barrel intakes work great and you can get the choke to be dead on with a little work. Get a good valve job and use valve springs for your cam. I'd suggest no higher lift than .500 so you can use viton valve seals. Get a cam about 268/.450 up to 280/.500 and use a good double roller timing chain. Repace all the seals and gaskets while the engine is out. Put in a High pressure oil pump and windage tray if you can afford it. You'll make enough power to have to use the 727 trans and still get decent MPG on the highway. Good luck.
