any1 using these? are u getting some good numbers with them?

 

I just dynoed 426hp with them and X1 with all boltons through cats. 400 unlocked.
yank ss4000, and on 11x17's

 

VERY NICE

 

Nice indeed.

 

Best bang for the buck on the market IMO One of my racing buddies is using them with great results!!

 

excellent heads. i have them and i am very happy.

 

I'm really liking this set-up, as that's exactly what NineBall dyno'd with the same set-up. Not only are those number impressive, but consistent, and that's the most important factor in a shop...repeatability (I think I just made a new word? )

 

I hope to be putting up some (track)numbers here real soon

Kick ***.

 

Why doesn't MTI use the larger valves that are in most other stage 2 heads. MTI uses 2.02/1.55 on the 2e....most are going with 2.02/2.04 and 1.57/1.575.

Now they do use the larger valves on the more expensive heads (2R's), but in the same price range of 2e's everyone else still uses the bigger ones!

 

The bigger valves aren't need in a stock CI motor...
