Offering a set of 2.0L Hoffman heads. Cut for 8.25 compression ratio with a 2590 cam in a 2056, would be higher in a 2270 (Len's suggested compression ratio with that cam). These are based on the AAPerformance Chinese castings, and have both the ceramic coating and the black heat dispersing coating. 44x38mm S.S. valves. Bought these for a build that won't be happening anytime soon. $2000SOLD! in San Antonio, can ship at your expense.
