If you make it into the 11's with those crappy TFS piece of junk heads...
Oh wait, did I say any of that out loud!!!
If those are the early 'twisted wedge' design... all I'll say is GOOD LUCK!!!
The second generation of TFS small block heads were basically a aluminum clone of the GM Bowtie Phase6 head. THAT was a decent offering.
So I'm with the ripdawg... unless everything go much better than the 'typical',,, high 12's
