TFS 220s as cast with a little tooley massaging...
we are all assuming 3.90 bore heads if they are for 4.00 bore or bigger that should be listed...
plus flow numbers can be generous on certain machine what did a stock head flow...

WE HAVE A WINNER
Haha!!3.90 bore with a pipe on the exhaust.
Two things really surprised me.... They flow a little better at at some lower lifts than the CNC 215's and they picked up 50cfm at .600 on the exhaust over the advertised "as cast" #'s on the TFS website. The car is at RPM and will be tuned tomorrow.
Anyway I was really impressed with the #'s and hope the track will back it up. I had mid-high 11's HP with the old setup but only ran a best 12.02 so we shall see...... The fact that it is lowered with heavy wheels doesn't help my times but it is used as a streetcar with runs down the 1320 for ***** & giggles

yup i was impressed with the numbers too, i just helped someone flycut for those heads with a polluter car...they are running the same 57.5cc as my heads...TEA said they were going to mill them to 59CC but when we checked last weekend they were 57.5cc...so you might want to make sure you check PTVC, not sure if you are milling or not...
