What valve-train set up does the SE MVA Heads have ? Type of valves, spring, seals, guides ect ? Motors comin apart so nows my chance to upgrade this area. Maybe fueling spring kit? whos valves are best ? finally who should I send my heads out to set it up? Tman ? any suggestions

 

Give Larry a call. He is the Head Guy that we decided to use on our 120R crate upgrade. We (builder Jim Kennedy) and I decided to buy a couple of 120R's and see what else we could get out of them. Doing Tman 662 cams, S&S roller rockers, HPI 62mm TB for FBW. Larry got the heads to flow 330Cfm from 295Cfm stock. The man knows his stuff. Not a fancy website but he is one of the most respected head guys in the business. There are a lot of excellent folks out there, just do a search and see the # of hits that come up. Depending on what your wanting done, there is a porter for every budget.
Some pics/discussion around our headwork is here http://harleytechtalk.org/htt/index.php?topic=33658.0
Larry's website is http://larrysmotorcyclemachine.com/1.html

 

So the MVA heads that come in the 113 kit and the heads on the 120R are the same?

 

Except for the 120R badging...
