SBC 882 heads?

acquired a set of 333882 SBC heads - would these be any good on a street performance engine or are they garbage? Thanks-

Cool link! They appear to be 73-80 360 and 400 heads with 76cc chambers, I assume 1.94/1.60 valves? Anyone know what they flow? Are they the lightweight castings they get such a bad rap? I have a couple sets of possible heads for the coupe, I intend to use about a .480 lift cam with single 4 barrel and manual tranny and am trying to decide which heads to use. Thanks-

 

Dan,
I raced a '74 Corvette in NHRA Stock class, 350 w/#882 heads. The flow on the exhaust side is pretty poor, and the intake side is marginal at best. The heads have a tendency to crack, and are factory with 1.940 intake valves and 1.500 exhaust valves. Now, we blueprinted the heads to 63.3CC chamber size, and with all stock components and a NHRA legal "cheater" cam, we made 390HP @5400 RPM.
So, depending on what you want for power, and your budget, thats the facts.

Dan,
You will find this link to information useful.
Good luck.

 

Those heads were made in Mexico. Very poor castings that crack easily..
