Hello.
Does anybody use S&S 110 sidewinder kit for TwinCam 07-later?
Can you advise me, is this kit compatible with SE heads 17248-07 & 17250-07 ?
Thank you.

 

i used the kit with s&s heads. No reason why they wouldn't work with se heads. They are meant to function like stock hd equipment.

just check your clearances as you would in any other case.

instead asking randoms, why not call/contact s&s directly?

I`ve asked S&S first. They told me that they didn`t work with SE heads at all and didn`t knwo anything about compatibility )))
Actually I`m afraid, that valve relief o CP pistons will be not enough for SE valves.

 

Compression with those heads would be about 9.7:1, and closer to 10.6:1 with stock 103/96 heads.

 

Do I need machine piston relief for this heads?
I have ported 103 heads too, but without ACR. And I don`t have fixture kit to install it ((

 

If I had to have something that was supposed to be bolt on machined to fit, I wouldn't buy it. That's just me.

 

thats why you check the clearance. The 103 heads will work just fine. Have someone slap the acrs in if you dont want yo buy or make a tool.
