Which heads will work?

I have a '07 Ultra. I was thinking of buying a pair of stock heads to work with for future upgrades. Are the 88" heads the same as the 96" heads?? Thanks.

the ports are bigger on the 96 and shaped slightly differently.
I believe they they bolt up the same, but I would check with a dealer or builder.

If you are having the heads ported in like a stage 2 fashon get the pre 06 so you have the good 5/16" valves and springs. The intake flanges would have to be changedto the earlier. If we were doing the porting in like a stage 2-1/2 of stage 4 it wouldn't make any differernce to us because we would be replacing guides, valves, and springs. Other porters do it different.
