peej410 Posted March 31, 2004 Share Posted March 31, 2004 hey i found these on ebay they are in jersey a few hours away from me the guy has a buy it now of 150 and they have been freshened up, if im not mistaken a set of used heads is worth at least that. they look much better than my crappy 882 heads but i cant find their casting number anywhere except for one mention of a "goodwrench saga series" or something 93417369 is the casting number and heres the link, let me know what you peeps think, im just getting into this stuff and i want some opinions thanks in advance - pete http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2469885168&category=33617 Quote Link to comment Share on other sites More sharing options...
Mike kZ Posted March 31, 2004 Share Posted March 31, 2004 Are you sure that first number is a 9? This is what I found: 33417369...90-up...350..........Gen.I Goodwrench crate motor, "Hecho en Mexico", 76cc Quote Link to comment Share on other sites More sharing options...
peej410 Posted March 31, 2004 Author Share Posted March 31, 2004 thats the number the owner gave in the description. i emailed him about valve springs and the like and for more information. i wanted to bump up compression a little bit seeing at my motor is completely stock and i saw the intake ports on my heads when putting on my manifold and they are almost half the size of the gasket holes im pulling the motor later this spring to check out the tranny check out the clutch install a new crank dampner do the heads and cam. everyone says to do vortecs but id rather not buy a new manifold because this motor will only be in the car for another year or so . i might even part with it and build up another Z so i want to spend as little as possible - pete Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted March 31, 2004 Share Posted March 31, 2004 you need to carefully think out your goals and budget, and match the engine components and gearing,this is not intended to be an exact combo, rather its just a way to get you thinking I really hate to keep pointing this out but its a flat out fact that a good set of aftermarket heads matched to a good performance cam are the best performance upgrades your likely to add to an engine, Dart Iron Eagle 200cc/64cc heads 2.02/1.6 valves, your choice of angle plug or straight plug. 7/16 or 3/8 studs and guideplates. They come with a performance 3 angle valve job and professionally assembled with Manley Race Flow valves. Springs are 1.46 diameter crane dual spings that will handle a .600 lift. http://www.parts123.com/PartFrame.asp?ZTM=cadegeca&GHOME=www.dirttrackthunder.com&TITLE=Dirt_Track_Thunder yeah, Im aware moneys tight and those stock heads SEEM TO BE a good deal but trust me on this! youll kick yourself for wasting the money later if you buy stock heads. read this http://www.chevyasylum.com/chp/Welcome.html then look over this carefully http://www.ryanscarpage.50megs.com/combos1.html the one thing you should notice is that ALL the better combos have aftermarket heads and a cam that takes advantage of the better flowing heads btw http://www.holley.com/HiOctn/ProdLine/Products/AMS/AMSM/300-36.html you can pick up one of these intakes on EBAY NEW for about $125 or less and they provide excellent performance with most street combos, an easy 15 hp or greater improvement over a stock cast intake on many engines matched to a cam like this it can be a very noticable improvement http://www.holley.com/HiOctn/ProdLine/Products/IEC/IECC/Chevy4.html Best performing REAL street cam.

peej410 Posted March 31, 2004 Author Share Posted March 31, 2004 as always grumpy thanks for the exhaustive input. i realize a set of good aftermarket heads are worlds better than stock but if i was going to spend 700 dollars on heads i would build a bottom end thats worthy of them. my motor is a recon (read sh*t) rebuild. all the spring retainers are different the crank has .015 endplay (vaguely remember thats out of tolerance). because i decided to make my own engine mounts to my frame rails i bought a used weiand single plane manifold at a swap meet for 50 bucks and used that to mock the motor up so i could eventually run a tall manifold and keep the stock hood. anyways, this motor doesnt deserve alot of money or a 700 dollar set of heads or to be honest even a 500 dollar set of heads in my opinion. i want to do a cam just to play with it and learn something about motors, i was going to even use a used cam sourced from another hybridzer but i havent decided yet. i figured while i have the motor out i could get rid of my crappy heads install a cam install a new crank dampner and a new crank pulley (need to be replaced) fix my oil pan leak and keep my manifold and edelbrock 1405. then this winter build a motor possibly. right now money is tight but i have tons of time to play, anything is better than what i have which is why i posted if these were any good. BTW i do cut and paste every response youve given me so far about engines and cams and the like to files on my computer so your efforts arent wasted thanks -pete Quote Link to comment Share on other sites More sharing options...
Guest 77vegasz Posted April 3, 2004 Share Posted April 3, 2004 If you are playing around and on a budget, I would suggest looking for a set of 305 heads from a camaro. I have seen plenty on E-bay. They will raise your compression as they have small chambers, and can easily be opened up to accept larger valves. In fact you can probably find a set there already done for a decent price. For what you are doing, this would be a good comprimise. Jon Quote Link to comment Share on other sites More sharing options...
peej410 Posted April 3, 2004 Author Share Posted April 3, 2004 thats an idea i like, if it would stop raining id head up to my favorite speedshop and see what they say, they think im insane though hehe Quote Link to comment Share on other sites More sharing options...
David K Posted April 3, 2004 Share Posted April 3, 2004 Look at the heads here, i think this is what you are inquiring about. A couple of pages of info on this site about those heads http://cf.geocities.com/ecric22/page1/ http://www.rustpuppy.org/chapter1/chapter1a.htm With the heads together I went back and checked the cc volume of the combustion chamber to verify what the 0.040 head milling had done.. It was neat to find a volume of 69cc.. I had expected 70 but that was just a close approximation based on area measurements of the 400 head.. While fooling around with the heads I verified the exact casting number. Chevy High Performance has the number wrong in the Goodwrench Saga series. They have it as 83417338 but it is really 93417369.. The nines on the ends do look like eights since the casting is pretty rough but I did a really close inspection on both heads and they are definitely nines..
