I say look back at one of your old videos of the TBI head, because you did a lot of work on that fin, even adding clay IIRC. I remember there was a lot of counter intuitive behavior depending on where you biased that fin. So that might be a good refresher to see how you want to proceed.
Do you use a squirt bottle of dykem to get the pattern on the port and cylinder wall? Any issues with shortening motor life? Do you have a TCM25 that you use for your valve jobs?
@@amirdoshmanfekan5145 As the air volume and speed through the port increases the air has a hard tike following the short side. When that happens it starts to seperate and window out across the valve. This reduces flow.
It would be interesting to get your hands in a set of GT40 heads that someone else done to see the flow pattern. I bet they won't be the best either?
@@dondotterer24 Depends how they were done.
@servediocylinderheads Yes.
not behaving as predicted .can't wait to see how you .adjust and move forward..Great job thank you for sharing
@@clarkmcmahan1595 I got it.....almost. Thanks
No doubt in my mind

I watched them last week. Funny, but true.
Tough results.

@@65mustang393 I use areosol dykem. It is dry before it gets to the motors. I use Sioux stone equipment for valve jobs.
@ thanks for making awesome videos man!
@65mustang393 Glad you like them. Stay tuned!
Why shortside effect on high lift flow?

@servediocylinderheads so to solve this you decrease the air speed at the floor?
@@amirdoshmanfekan5145 If possible.
@@servediocylinderheads thanks charlie
@@amirdoshmanfekan5145 No problem
What castings are they
@@craigtripp5509 C6FE castings
Must be nerve wracking, working on rare valuable heads with no test head to analyze and cut apart.
@@donthompson2188 A cutaway would make this much easier, that is true. Core shift can always bite you. Thanks
