Just ordered a S&S 126" with the B2 heads I think that might be like a stage 6 or something lmao muuuaahhhh

Just ordered a 100”power package with 585 cams for my 06 fuelinjected fatboy. Im also looking at the 89cc heads as it says the 79’s arent compatible with this setup also thinking about the crank which one would i go with from s&s and what kind of power should i expect i know it says my compression ratio will be 10.2:1 with the 89 superstock heads

Can I do the super stock cylinder head kit with my bone stock engine or do I need to get the bore kit first, the bore kit is like 5 grand & this cylinder kit is like $1500

Hard to build up the early Twin Cam engine because of the weak compensator & they're not making a better compensator for the early engines. Best Twin cam is a 2014 and up , Harley learn how to give these engines an better compensator, at least.
