These are off an 89 Corvette L98 that had a ZP 6 speed if that helps. I do not have the casting numbers with me at the moment, but I am looking to sell these heads and just need a ball park figure. Any help would be appriciated!!

 

if they r l98 alum heads it depends on the condition. i would be intrested in them cause i just want the castings. I know alot of people have been asking about them and i guess ill just shot an offer too hows 200 + shipping to 60433 sound

 

Condition looks to be pretty good. They were very clean when i took them off the engine. I'll try to see if my mom can find and bring them over to my house tomorrow for the casting numbers.

 

They should be the 113 casting . Those r the last 3 digits of the #

 

yeap casting number 10088113

 

Id say their worth about $150 per bare casting.

If your interested in selling,

im looking for a set to put onto my 305.

LMK,

Sheldon

 

They fetch $400-$500 on Ebay.

 

They are worth more to Corvette guys than everyone else most of the time. Reason being, Corvette guys want them to keep cars original, but for guys doing performance mods, those heads usually aren't worth the money and trouble, because they don't flow any better than factory iron castings... compared to many, they actually flow worse. The 416, 601, 081, 083, and 993 castings all outflow the Corvette 113 heads, on both intake and exhaust sides - in stock, unported form of course.

 

I'd have to agree that they aren't anything special IMHO, but FWIW, when I was considering a set of 113's for my iron headed 85 Corvette, it was the "Corvette guys" that said they were only worth $250-$300. On Ebay, I had seen two different sets go for nearly $500 each set, which is the only reason I threw that out there. Personally, I thought it was dumb to spend $400-$500 for a set of used heads, then have to spend another couple hundred to freshen them up (assuming they were only in need of a freshen, of course)...only to still have an "OK" pair of heads.
