I have a stock 07 96" engine. I have just purchased a stage 2 103" kit with the SE 255 cams. I wanted to know what the size of the stock 96" combustion chamber would be? I came across a set of Screamin Eagle 110 heads and was wanting to know if they can be used on the 103" kit. Does anybody know what the compression would be with the 103 kit with the stock heads? What size the compression chamber is on the SE 110 heads? Will the pistons need to be changed to work with the 110 heads? Any other info on this would be greatly appreciated.

Thanks.

 

My 08's 96" heads were 85.8/86.

 

Without part numbers for the Stage II kit or the heads, can't say for sure. The Stage II BB 103 kit includes flat top pistons which will work with your stock heads. The SE110+ heads have a chamber volume of 95cc and you would need pistons to match to get the compression up where you need it.

JMHO but you would be better off to use the pistons in the kit and port/deck your heads for the compression required to make the 255 cams happy.

 

Thanks for the input.
