yes I thought the same thing, its got to be a TYPO, or he means 882 heads
882 heads are THIN castings that provide about average SBC OEM performance.
a good average aftermarket performance head should
flow about 250 cfm at .600 lift
even stock vortec heads with some port and bowl clean-up should flow about 230 cfm at .600 lift so the 882 heads that generally flow about 206 cfm are not all that impressive, will they work on a daily driver? sure but ID look for something better if performance is the goal
