These might have 500 miles on them. New I bought them from jegs for $1500 in feb. 2010. I need to get at least $1200 out of them as they are just slightly used. They are still alittle dirty from oil and normal combustion from the chambers but I was going to clean them up before I ship em. I still have the original boxes these came in, will also ship out in those padded boxes.

I took photos of my stock 452 casting heads to compare the difference.

Exhaust ports

 

Wow looks like the factory really didn't want much exhaust flow..LOL

 

Even the intake is far greater then the factory heads.

 

Valvesprings on heads are good for .600 lift, combustion chamber size is 84cc.

 

That is not a bad price for those heads. Good luck with the sale.

 

Too bad I am not doing another 440, would buy this up, got the same set with the same rockers you have in the other posting.

 

Yeah they are very nice when paired together, to bad I was unable to really make this motor run my putting a cam in it. Reason for selling this stuff is I am putting a small block in the truck so I can daily drive it again.
