I’ll say this outright, if the head is dead stock, then as I type away right now, I have no idea how to do it.
Could I figure it out? IDK! I’ll just say I’m not interested in trying but hearing what others do and how they went about it is always interesting and welcomed.
Now you said GTX John went 11’s in a 4,000lbs ride using 302 heads.
I think that’s cool. I would assume there ported, but if there not, even better. I’d like to know how it was done though I don’t think I’ll ever hear or see a class racer talk & type about there stuff ever.
Now can you define power finally?
