Really nice set of 862 heads with REV stainless valves. Intakes are 2.055 exhaust are 1.57. I got them used and had a valve job done and while he was at it had the chambers CC'd and they came in at 63cc's. My machinist checked the springs that were on the heads and said at install height had 115lbs. And at .550 were 285lbs. I could not find a porters logo anywhere but the machinist said they had done a very nice job on the CNC program as there was no signs of clean up anywhere.
I've got pictures on my phone PM me your number and i'll text them to you if interested.

Any flow numbers? Also, what springs do they come with?

Intake runners measure 220cc. I didn't check the exhaust. I couldn't find anyone but Lingenfelter that uses the REV valves, but they said that there should be a logo. The machinist said there was a nice rock-over line on the short side radius which is supposed to help with low lift flow (idk). Springs are unknown. Pressures are as advertised above. Between the Valves and the machine work the CNC work is free. Put what ever valve springs you want on them.
