I've had great results with TMan 585s in 110s. A little pocket porting with a 1.95 Intake and our custom
intake seat profile makes a nice flat TQ curve. Bronze guides are standard procedure here.

There's a couple dyno sheets on my website you can look at. Lot's of ways to skin this cat!  You make the
TQ nice and flat, the HP will come by default.

I see, said the blind man..SE 585s, TTS 150, and CR 575s will make 120/130 with headwork in a CVO 110(good pipe and tune of course) while the Tman 585 makes 130/130 + or -2 with headwork and a good pipe and tune of course..So with headwork what are the SE 117 kits from suburban speed or tman making hp/tq ??

A 2.12 valve is way too big for that port IMO. (The throat needs to be the smallest point in the runner).
With a 2.12 valve, a 90% throat is about 1.9". The port opening needs to be even larger than that for it
to work properly. (That puts the port opening close to 2", Way too big (unless you just want top end HP.
A huge runner like that will kill your low speed TQ)

This is where a flowbench can mislead you and take you down a rat hole. (A 1.95 valve is plenty big for
that application)

Food for thought is all. But what do I know?

The results speak for themselves. The stock 110 and the 2.12 valve corrects for too large throat percentage and works great with 10 degrees less duration than the tr585 plus a half to three quarters point less compression. Throat at 90.3. Flow bench is what it is, dynos and torque curve plus street manors are what count. Plus many cvo owners won't give up the se110 logo on those heads for the stockers. Just another way to skin a cat.

Thanks Don,

I am going to try the TTS 150s first...I have the SE 585s now (no headwork)...but thinking ahead would you recommend the CR 575 with your headwork in a 117 build if it were just between these 3? I know Tman has a few great cams with your headwork making 130/130 minimum, but i dont care about h.p..

Those tts150 are strong with my head work. The cr575 becomes pretty short for a 117. The tts150 is the torquer and is little more appropriate for the 117 at 10.5:1.

Thanks Don!

Don,

With your headwork would you run the SE 117 kit as is or change pistons to that 10.5:1?

The kit pistons are fine. 0 decking is prefered.

If you need that size valve to make the throat correct, then that's the only option other than pulling the seat rings and welding it all back in. IDK why they do that $hit.
