882 heads

I think i am getting a bad rap i did allot of reading and everybody tells me that these heads are not good but a article i found in chevy performance says otherwise for my applcatoin.these heads flowed as good as the vortec and even some of the aftermarket heads up to 5500 rpms this is were the drop off occures and the other heads win out. this is the question how many of you are going to bang through the gears above 5500 and, one not get busted on the street and two have a open 1/4 street to race on in town where i live you better have a bail bond card in your pocket. I agree if i was racing allot i would find some nice heads but i am building a 23t bucket and probaly most of us have a street rod or a street machine that we get to open up a little bit between light stand we really never get to hammer down they we would love to.

The 882s are good flowing heads, but they're light castings and a lot of people say they are crack-prone.

There is absolutely nothing wrong with 882's. Yes, they are a thinner cast then most but if you have a sufficient cooling system there is no problem. Crack prone is what many people say but if you don't get them hot you have no worries. I ran a set for years with port work on a 355 and had a little more than 400hp. That is plenty of power in a t-bucket to disintegrate alot of tires.

I'd say they'll work just fine for that light bodied tbucket, hopefully you have the 1.94 intake valve sized version, many of them were only 1.72 versions. The 441 casting is even better, same basic flow as the 882 but a lot thicker casting. You can spot the 441 easy by the 1 rectangle casting mark on the end of the head. Drawbacks to the 441 is no hardened seats.

Run the 882's with flattop pistons, steel shim headgasket for a quench distance of .040ish, 268ish duration cam, headers, dualplane intake and 600 carb and it'll make all the power you'll need for the street.

I have both the 441 and 882 castings. You say that the 441 doesn't have hardened seats but the motor they were on seemed to run fine. Also i believe the 441's have 2.02 valves on them.Which ones to use. Would the same go for the 441's as for the 882's with the steel shim gasket.

882 heads

i would check with a good machine shop the 882 are said they are prone to crack but that only goes for people who dont take care of the car the 882 have 76cc and some come with the smaller valvas so i put in the 194 chevy hi performance magazine has the article on flow of the heads
76cc heads i had to go with .125 dome pistons to the compression were i need to. dave
