I am looking to build my TC96 in my 2008 FLHX to a TC107 with Wiseco 10.25/1 Pistions, Woods TW-777 cams, power commander, 50mm throttle body and my 2002 heads from an earlier 97" build that produced 111hp and 113tq in my 45mm Mukuni carb'd 02 FXDWG3.

The heads have been ported, polished, cc'd, 3 angle valve seats, Manley 1.94 intake and 1.615 exhaust stainless valves and .650 lift springs. I've already had the front boss machined to accept my front engine mount on my FLHX. Question...am I correct in that these TC88 heads will perform great for my 107 build?? Not looking for the last hp or tq#...just want a good running bike again.

Used HD parts bring about 0$ these days, therefore I believe it would be a waste of time to try and sell the TC88 heads for $500 and place that toward reworking my stock TC96 heads. Yup, I've read that TC96 heads flow better than stock TC88 heads...however is there any major improvement in a ported set of TC96 heads over equally ported TC88 heads??

I'm thinking this 107 combo should put me in the 115ish hp and 120ish tq range.

Opinions??? Thanks guys.

 

If the port job was done well they should work fine, the castings are basically the same, MOCO just opened up the exhaust ports more on the later model heads. I'm thinking you'll be more in the 110hp & 120+tq range, should make a good running engine though.
