Man you guys are the real deal with a machine shop. Badazz
Interesting. I enjoyed learning from you!
How much do you charge this will be perfect for my 128 build and what cfm did they flow ?
Nice looking work and using Star parts means you know what tf your doing!
LOL
Nice video! About how many hours does it take produce a set of upgraded heads, starting with the stock heads? Thanks!
It just depends on the job...some take a little more work than others
What do these heads flow iam a head grinderwith 55 years of racing head experience stock 114 heads with porting and stock kibble white valves at 600 lift intake is 345 cfm and the exhaust is 268 cfm if ported right your heads look to be to big witch means no velocity just volume I ran Air flow research for 18 years make them smaller and good luck
Yes, you are correct. Thank you. We no longer flow heads.
Nice👌
cool!
What do they flow at 200 to 400 lift intake and exhaust 28 inches on a super flow
We no longer flow the heads anymore.
What valve grinder did you use?
Quikway
You know those stem ,heights are way off lol
On your heads. Intake side only cut the throat 87% of valve area on m8 heads for all .500 and and up to .550 lift cams. Go 88% max on cams over .550 lift. Example on a 42mm valve cut the throat to 36.54mm.
Do you have good ratios for the 103 TC heads? Good tech info!
@@trailerparkcryptoking5213 Don't go over 90 to 91% on 2 valve heads.
