Are 882 SBC heads good?

The 882 heads are smog heads from '74 to '80 and not very well regarded, but neither are stock '85 heads - if you can find out more about the 882's they may be better than your stock '85 heads - ie not only polished & ported but if milled so they will give higher compression and if valves were changed to 2.02 etc they

Consequently, what are the best SBC heads?

Beside above, what are double hump heads worth? 461 and 462 double hump complete heads should be worth or priced at $200 a set at the very least. With all the choices in new motors and heads these do not have the interest they once had.

People also ask, why are double hump heads better?

They flow better have more efficient combustion chambers. You can run more compression, less timing, and less octane and make more power with Vortecs.

Are 441 heads any good?

The 441 has a reputation as a good-flowing head among the production 76cc chamber heads. In this particular case, it lost out to the 882 head, but overall it's a decent head that responds well to pocket port work and larger 2.02/1.94 valves. Its small 155cc port volume creates great torque and excellent driveability.

How much horsepower does double hump heads add?

"Double-hump" heads were found on many of its high-performance engines in the 1960s and early 1970s. They were manufactured with larger intake and exhaust port volumes and valves for the period, and engines equipped with them had output ratings of more than 350 horsepower.

What are power pack heads?

The "power pack" heads have 58 CC combustion chambers, and smaller valves than later heads. They were used on high-performance models of the 265 and 283 engines, and were also used on the standard 195-horse 2-barrel 283's in the later years of that engine.

What's the difference between 461 and 462 heads?

Are 906 Vortec heads good?

the better of the 2 are the 906 casting heads because they have like 20% better flow over the 062 heads. 062 heads come of the 3/4 ton trucks.
