looking for a set of square port heads for bb chevy for a friend...........oval ports if i have to, and then a performer manifold to match the oval ports...get with me

I've got a set of bare 990's (?) that may need to be worked over.

If the heads are for a jet boat, you'd be better off with the large oval port heads. From what I've been told by several jet boat pros, they're much better for mid-range RPM than the rec port heads.

How much $$$?

how 'bot for your droop snoot?

how 'bot for your droop snoot?

Sure, as long as you throw in a Rooster Booster. 

... I'd would be open to trade for a droop / droop snoot -I've been wanting to see what, if anything, it would do for my ride...

I think I might have found you a droop snoot, I'm working on it...

These were on my jet boat.  I read somewhere on the 'net that these were used from the mid 90's  and later for Marine 454/502 HO.   They were stock on my boat -never removed or worked on.  I burned up some valves the summer prior and... long story short, I went with a new a$$ebled set and these have been in my garage since (bare).  They have been magnafluxed and from what I was told these can be worked on -I didn't have to time to wait, hence the new set.  I don't have the know-how to es'plain much more other than that these are heavy ass paperweights that bend wood shelves when stored too long. 

If you're local you are more than welcome to take a look.  I'd rather hook someone up on the boards for a reasonable price than make a few bucks on a random shmuck.  Karma.  I'd be down to trade for any jet boat goodies.  A droop/snoot + $?  or anything to make me as cool as you guys... 

what size valves are the heads set up for?..open or closed chamber.....and yes its for a jet boat, duh...

***another question...can a square port manifold "work" on oval heads...tring to save some $$$$ here!!

You can use a rect/sq port intake on an oval head as long as you use rect/sq port intake manifold gaskets.

I have a set of 049's but I wouldn't part with them until after I've got a set of rect port heads. 

Legal Chemistry, PM sent.

I phoned the local guru's and... uhg... must have thought I was completely stupid, told me both 049's and 990's cores are worth $100 - $200. NOT. Someone told me 049 cores are worth $200 - $250 (ea) and 990's $250 - $350 (ea).   

Be careful if you go 990's because they have been discontinued.

Haven't the 049's been discontinued for a long time as well? Weren't the 990's replaced by the identical 880's which are put on marine crate engines?   

Here's some cut/paste info from a quick search:

14097088 1989-94 502 Open GEN V, 118.0cc, IP 325cc, replacement

14097088...91-up...rect...OPEN...Gen.V 454/502 HO, 118cc chamber

14097088 Iron      Cast   Open 118cc  I: 2.19"  E: 1.88"    325cc    Rect.    Square    use with Gen V big-block engine P/N 24502618-20 "BARE"


I thought these were still used on crate engines?  Hotrod, was the guy you talked to looking to buy heads for that price -that would explain $100.

c'mon, anything to throw on the table.  My boat barge want to get movin' on up the slow river this year.   

'049's seem to be the most popular jet boat head I have seen run. Lots of jet boaters run them and swear by them. Chris Straub will even tell you that for a jet boat '049's are capable of some serious power.
