Yikes! I used to have them do it for $1695.99 that was CNC port work valve job and springs. I will say this I switched over to Frankenstein LT heads gained 3/10s and 5 mph on my C7 (10.11 at 138mph ALL Motor) and all it cost me was $1,150.00 me doing my own spring install. I tune LS and LTs but I don't use a dyno but could care less what that shows the MPH and ET spoke for the results.

Thanks man, it runs FED ported heads, FED ported MSD, LT5 throttle body, UD pulley, 2" headers, Circle D prototype converter, my own cam, MS109 fuel, Halltech carbon fiber intake, 15" conversion. I do have plans on having a 416ci built next year.

Nice man! we also built a C7 here but haven't done the 15 inch conversion and aren't running MS109 Yet, currently on e85 and it's running 10.6 @ 130MPH. Will upgrade a bit more soon!

If you guys need any help with it let me know. I've played with the 6spd and 8spd ones. Currently doing a twin turbo C7 Z06 for a customer.

Was that gain going from stock heads to FED or worked heads to FED?
