Are 882 sbc heads good?

Looking for an answer to the question: Are 882 sbc heads good? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are 882 sbc heads good?

The main difference between the 882 and 993 heads in regards to cracking is the 882 feeds the exhaust crossover from both center exhaust valves as opposed to the 993 which feeds the crossover from just one. That additional heat concentrated in the center of the head is the main reason for the cracking problem.

882's are the "Best" of the worst heads. They are the heavy weight casting. As noted, they are crack prone thru the center exhaust seats. They will flow fairly well if the intake side is port matched and the upper part of the exhaust port is blended.

Al Covin 's book CHEVY BY THE NUMBERS notes/verifies this oddity of the 881 & 882 Castings being excactly the same late in the 1974 year . Just sold an extra set of the good 2.02 /882 cast heads .

There are two different types of 882's - heavy and lightweight. The lightweight are crack prone, the heavy are not. If you want to only make 300hp, these heads will do it with some flat top pistons. The best factory heads are Vortec's that came on the last 350's, but they take a specific intake and centerbolt valve covers.

What is a Fuelie head?

It's two half-ovals connected by a straight bar-most easily described as "two humps."

“Super-sizing” may be a bit of an exaggeration, but cylinder head buyers have been known to opt for valves that are too large. That can result in cylinder heads that don't fit an engine's performance needs—or the actual engine itself!

Do aluminum heads make more power?

Premium Member. if it ran fine then run it, 882 heads usually crack when over heated in the exhaust seat area as Rick said, or or in-between intake and exhaust seats, and when they do there is evidence in the white exhaust from coolant in the exhaust. if the exhaust ports look uniform in color call it good and run it.

What's the difference between a Vortec 350 and a regular 350?

vortec 350s have a hydraulic roller cam, old 350s are flat tappet. the block is essentially the same but the heads are different. you need vortec specific intake manifolds, dunno about the headers. overall a vortec block will make more power with less money due to the heads, ported vortecs have a lot of potential.

882 head or 041 head, which one to use? | Chevy Nova Forum

If you are dead set between those two sets of heads, then I would go with the 041 with hardened valve seats. Those 882 boat anchors have a nasty reputation of cracking on the exhaust valve seats because of the dual heat riser passage. 10 to 1 comp on the street is still pretty good. You just might have to add some 93 octane to the tank.

Steer clear of the 624 and 882 heads at all costs. I have seen all SBC heads crack. For 76cc heads, the best thickest castings are 993, 339 and 336 487 and 441 heads are ok, but not as good as the ones mentioned above, IMO. And if you really want a good thick head that hardly ever cracks, the 185 is hard to beat.
