I will keep you posted, im hoping to run high 20's to low 30's on one stage maybe a 300 shot . I've been a 5.41 with the Brodix Track 1 KC 227 heads so i hope they pick me up a tenth.

Be sure and check your valve pocket locations of the int/ex, as there is a .085 dowel pin shift that usually requires the pockets to be cut addl towards the int. side of the pocket on both the int and ex pockets. the revised int/ex split[left/right] will usually fit [ie 60/40] ok. Most pistons will accomidate the cut, but measure the thickness to be sure your min is @ leaset .120/.140 for n/a or .160/.180 if using a power adder @ the very bottom of the pocket @ the vertical wall corner!

These are BAD ASS heads. I have been 5.24 @ 133.96 3150lbs, 275 radial in the 1/8 on a 275 shot of spray. I ran the same time with the Brodix 10X heads but need to spray 325 to get the same ET. That is the closest comparison I can give you. There is a lot more left in that setup, but I'm in the middle of building a procharged setup and havent wanted to get too agressive and hurt anything
.
Take alkyal advice and def check the valve pockets. We had to touch up the valve pockets in my motor.

You should have no problem getting into the teens, let alone the 20's once you get the combination figured out.

I've had a set on my car the last few years. I've been 7.82 at 180mph at 3400lbs. I made some changes to go faster, 7.8-1 compression changed to 9.5-1 compression, better intake manifold, etc...
Unfortanatly, lifter failure put me out for a little while. Bob Williams is a great guy to work with.

Been 4.96 @ 144 and 7.68 @ 181.5 with my 245rr's from RFD... 3400lbs on 275 drag radials. You will like the heads, they work!
