2 years ago i bought 25 brand new k20a2 heads from a place called cylinder head exhange. they got it from some surplus auction and did not know what they have. i got them each for 500 bux and sold them for 1300-1500. within 3 months, 24 were gone. i kept one and just sold it last year. needless to say, there is a lot of people doing k series swap. one guy in florida who bought one of my head email me to tell me he made 365hp with a k24/k20A2 combo. he had 15:1 compression with e85.
