i have no idea what flowbench he used. he told me he put a lot effort into these heads and I have no reason to doubt him.
i have to say I appreciate the man for answering all my questions
How much did that run you and how did you get Greg to hand port? I thought he was only doing cnc work out of HPC now a days
You can get Greg to do heads without HPC just on contacting him directly I would think....
Money off the Books 🤫 with receipt. 😉. IDK 🤐
Greg avg cost depending on base of the heads and how far your wanting 2 go runs Avg to Whoa there, seen Mast heads listed here with $5k worth of work...
All depends on how far one is wanting to go....
FIgure for work done would run $1200 to $2000 if Greg has a program for the TFS which I'm sure he has or one close to which helps with time which is money. He's easy to contact, whether his FB page or in a YB pm, it may take a little longer as he doesn't post everyday on YB. Think I may still have his number...and or contact information....as GG help me with setting up my ls3 valve train
Also corrected me about 3wks ago on Mike Jones cams and Billy Godbold's low shock cams.
I know your wanting a exact number in Cost... Generally idea till the thread starter post .... There all around the same cost depending on if they have a program...then a clean up of the Port....

Finally got around to work on my heads today . I checked the piston to valve clearance.194 on intake and .176 on exhaust should be able to miss a few shifts before the valves kiss the pistons.had to order new pushrods today my where to short I need 8.250 and 8.300 long. I set the heads up with 1237x and tool steel retainer with mini 8 locks. I’m particular just look at the valve
locks
400cfm @ .600.... With the right cam, that thing is going to fly.
I follow Minkyinks cam spec for now 255/269 @50 114.5+4.5 advance 702/683 solid roller . I’m just hoping to get the car in the high 9s on motor. I’m setup with a 150 shot if I want to go faster.
