Post 283 cylinder heads

I am building an antique 283 chevy. I've bored some of these to 4.00 inches before, but I didn't want to on this particular engine so there would be a little more room to freshen up in the future. Anyway, the bore size now is 3.935" and I am now trying to select heads for it. I was building this to Z-28 specs except I intended to use Sportsman 2 heads. Here is my delimma, many manufactuers tell me that I will have problems with valve to bore interference with 2.02 intakes, I know I can notch the bore a little with a hand grinder, and I do know that cam lift comes into play, but I don't want to buy heads just to find out they won't perform optimally. Has anyone been there done that on a deal like this? I have a hard time believing that .065"---that is only .0325" per side, is going to give me problems of any kind. I am aware of bore shrouding also, but I still didn't think this should affect performance.

If you have a set of heads you want to try. Can you not just clay the head and turn it through to check for clearance. If your exixting 202`s clear that way, i`d use them. I run 202`s on my 350, but thats not what you have is it? Just thinkin out load.

Just a thought... If you're going to use aftermarket heads, it's not going to look stock anyway. Whay not go to a 350 block. Or go to a small journal 327 block.

Hello glad to see someone doing the same thing as me.I just had a 283 bored .60 to 292ci.I have done alot of research on the pistons and the heads.The pistons that seemed to fit the picture and price range are the keith black kb166 .100 domed.The big valve heads will not clear the tiny bores and the 283 powerpack heads are just not the answer.The path i took was the new vortec heads.They are the small valves but you can't beat the performance and the price tag with anything else.

Well, i'm not going to replace the block, because I have the short block completed. I've had this thing since Noah brought it over on the ark. The pistons i'm using are the L2275F-60 TRW, with a .400 dome, which is not ideal for the Vortec combustion chamber, the dome will inhibit the good burn and swirl of the Vortec head. I don't have a set of 2.02's laying around, but you are right in mocking this thing up, I just guess I'll have to purchase the heads and trust myself that I will be able to make them work.

vortec heads are spozed to fit a 283 even only 60 over without any further machining. your domed pistons should work but you might have to get them machined. the heads will obviously fit a bigger bore. do that clay thing and forget about messing up the swirl pattern. 283 bored to 302 can make 475 HP at 12.1 compression. for the .060 over 292 cid 10.9 comp. w/vortec heads and speed pro L2275F domed forged pistons 64cc chamber. dont ask me domed how-much cause i only know what i read. didn't i just say i didn't want to type this again? <img src="graemlins/nono.gif" border="0" alt="[nono]" />

That is to much for the street with cast iron heads.I have tried that and the car runs very hot and overheats.If it is going to be a quarter car no problem.I would stay around 9.7-10.1 on any street rod with cast iron heads so maybe edelbrock is your answer.
