I was just informed from the machine shop that I have a craked head and that is why the valve seat dropped. So I am in the market for one or maybe a pair of good heads.

Sorry I don't know all the big block mixing and matching but I have a good set of 496 heads if they would work?

Thanks, blowncrown, but I'm pretty sure the 496 is a whole differnt beast, unless some on hear tells me otherwise.

28,
By the time you buy a used one (or two) and pay your machine shop to fix them and set them up for your cam, you would probably be better off just buying two new ones from GM Performance Parts and swapping all your valves etc into them. They are not that expensive if I recall and you dont have to worry about what you are getting.

another option would be the edelbrock alum. heads , i priced them not long ago and they price between iron and other alum heads on the market

I have a brand new set of AFR 305's. CNC'd 114 CC combustion chambers, hydraulic roller springs, Inconel exhaust valves, and anodized.

I bought them for a 509 build then decided to go 557 CI, and bought a set of 315's.

The AFR 305's are brand new, as I said. Please PM me if you're interested.

I have 4 sets of complete marine take off's . They have stainless steel intake valves, inconel exhaust, guide plates, springs, retainers, ect....$400.00 per pair as is. If you want them freshened I can do that for an additional cost.

Thanks for the replies guy's. I will becontacting you for details.

Kidnova, I sent whipple an email to find out if I can even use those without major modifications. I only have a MEFI 1 ECU, so I'm am somewhat limited, or I go really hog wild.

Dean, that is what I was looking for. Any idea how many hours they have and how much it'll cost to freshen them up. Maybe I should at least put in new exhaust valves?

I will work you up a qoute and e-mail you back. The heads have about 300 hours on them. Yes they should be gone through. I will let you know.

I have a set of heads just removed with 500 hrs on them-they are in great shape. Came off one of my stock 500 EFI's. 2001 model 38' Fountain. I came across a new set for <<< and put them on for giggles. Will sell the set for $600 complete.
