[Tigers] 289 heads

[Scott Hutchinson]

I had heard somewhere that the 260 combustion camber was actually quite good. 

Faced with the same dilemma that you have I went with 289 hipo valves in the 260 head.  Very happy with the result, but you need to be VERY careful about piston valve interference. 

I had to advance my cam four degrees to make it work. This is with a comp roller cam, so the ramps are pretty steep. The cam itself is not that aggressive when compare to say a 289 hipo cam, but the roller aspect of it gets the valves open and closed fairly quickly. 

Amen on all the porting and polishing.
