Thread: head casting numbers

Tweet

friend just picked up some heads today. the numbers are,
on one head it has GM-6-14014416-21
the other has GM-4-14094093
anyone know?

can't use both. I have 416 castings on my 350 and it does ok. they're 58cc chambers. I think the 093 castings are TPI 350 heads with 64 cc combustion chamber

if I were you I'd look for another 093 casting. It won't have the compression that the 416's have. I originally had 882's on mine and with my camshaft 8.1:1 compression would suck so I used my 305 416's. Those 093's will flow better. Give them a good port and polish and it would be good. I had to check and see what you were putting them on I forgot you were putting a 350 in a 2.8 camaro.

i see, thanks. my friend ended up giving them to me anyways. looks like more money i dont have lol
i got a set of 882's as well

are 882s worth using? i definitely dont have the money right now for another head

882's are great for use as weight in your trunk. I had them they're 76cc heads and drop compression pretty bad.

goto the junkyard and look for a matching head for one of the two taht you have. I'd go with the 093's you could run regular unleaded then. with my 416's I have to run premium with octane boost. I read somewhere that they flow better than 882's even though they have 1.84 intake and 1.5 exhaust. If I had the money I would get a set of those world 305 heads.

ill look but im going to use the 882s for now

I'd hate tosee you goto the hassle of putting those heads on and not be happy with them and have to take them back off. where are you?

lol ok I thought that was a star trek thing, where's that at?

your killin me lol. its about 20 minuted away from detroit

cool I learned something new today. Get on that thirdgen website and see if there's anyone close with some heads. A lot of people there upgrade to vortecs or another aftermarket head and have theirs laying around. You're about 3 hours from me. I don't know how much heads cost at the salvage yard. I had a stock 79 350 in my firebird and it didn't do too bad. Wasn't anything great. I did some work to it and now it's a fun car to drive.

ill have to get some money together. but i gotta get some different pistons first

I never built an engine before so I wouldn't have a clue about pistons. If you're building up and have the time to save I'd definitely get a set of vortecs. They're about as good as it gets for factory castings. If you're gonna put in new pistons you could probably get a dome piston or something and do a port and polish on those 882s and have some decent compression. and flow good. I read somewhere that those 882's were thin castings. or you could put flat tops or dished pistons in it with some good rods and a crank and add some forced induction or NOS. I understand what you mean by being on a budget. I scrounged, saved, and collected parts for about 6 months before I put it all together.
