RC Engineering Head / 5mm Kit:
 Cylinder head modifications:
This RC cylinder head has been fully ported with combustion chamber blending.
We corrected a few things and added 34mm intakes. The seat area was opened up to 86% of the valve size for a proven performance upgrade.
The combustion chamber has been opened to 62mm which would be perfect for you AHRMA folks.
Surfaced to minus .019
Heli-coiled cam tower area with longer coils for strength.
Valve guides have been installed, reamed and a muti-angled valve job was performed.
We have this head nearly completed .... Until a camshaft is selected. At that time valve to valve clearances and spring pressures will need to be checked and set. 

Race proven Kibblewhite 5mm valve kit:
These kits have been used in the TQ sprint car world for decades and proven to be reliable. The TQ cars have been known to exceed 12 thousand rpm consistently.
With these lightweight valves ... Spring pressures can be set lower to gain power and make life easer on valve trane components.
Note:
Add lightweight Titanium adjustor nuts and lighten rocker arms for the full benefits of this kit.

"Big Air" Honda high-performance cylinder heads. 
These "Big Air" heads are some of the most powerful Honda heads ever built.
This highly modified cylinder head started life as a 77-78 F super sport head with special built 5mm valves, bee-hive springs and hundreds of hours in porting and combustion chamber work.
Now for the fun part ...... These heads produced over 124HP on a TQ midget chassis dyno with only a 67mm (900cc) bore.

66MM 860cc Big Bore Kit Combo ( K and F models)

Kit includes:
CycleX stepped sleeves for no upper case boring in most cases. (great sleeves)
JE pistons with armor glide coatings.
66mm bore (2.5986)
Comp height .940  (Basically 12.5 to 1 with a K model head)
XA6600 ring set.
Generous valve pockets for oversize valves.
