They have 2.02/1.57 Ferea valves & Comp 918 Springs. This was a $1300 port job from GTP at the time they were done. Im asking $600 for them and have the orginal receipt from GTP when they were ported. Have about 6k on them since the port job. Only thing out of the ordinary is that two of the valves were replaced after a bolt made its way into the combustion chamber and scarred them up... They were just at the machine shop being checked out and cleaned here are some pics...
These were flowed independently and the intake cfm peaked at around 270. Stock 806 heads flow around 215-218, stock 241 heads flow about 220-222, and 243s are about 250cfm im told....
