If you look at the valve events, the difference is only the earlier intake closing and a slight change in exhaust opening (even the lift is the same).

JD vs. TK
IVO: 6.5/6.5
IVC: 43.5/45.5
EVO: 58.5/57.5
EVC: 6.5/6.5
And resulting overlap is the same.

Either will give you more top end than the Howards ASA. Between the two the Junkyard Dog would be a better choice, as the IVC is closer to the ASA therefore mid-range should be similar. Which is probably why they recommend a slightly higher minimum stall range on the Titan (min. 3600). So for your gears and stall combo, JD would get the nod.
