rocker arm question
so I am working on putting together a budget 107 build for my 2009 cross bones. Currently I have carls speed shop ported heads, wiseco pistons and cylinders, and woods tw9 cams and s&s pushrods. I know I should probably get new lifters and rockers. My questions is this, will stock lifters 1.625 be enough for the high lift cam(.63)? I'm obviously trying to do this on a budget, but I also want to keep my bike reliable. Also, I have a velocity stack and open pipes that i like cosmetically so understanding that with a good tune what kind of dyno numbers you think im looking at? Thanks.

Of course how hard you twist the wrist makes all the different

The ratio is fine but with a lift over .600 I would be looking for some roller rockers. Valve guides have a longer life with less friction on the valve stem. S&S makes good ones though spendy. I would also get their lifters or Woods lifters. Stock lifters will make it pretty noisy and not last long IMO.
Roller rockers do make some noise bout like a sewing machine but worth it. I'm doing a similar 107 build and am looking for 110/110. So many variables though and strait pipes will sacrifice tq even with a good tune.

Thanks man. Are you doing labor yourself? If so do you have a lot of experience?

I do mine own assembling is all. Dan Vance will be doing the porting on my heads as he did on my last 124 build and boring my cylinders, then when all things are assembled together it goes. I do a deck check, pinion runout check, set the ring gap, and clearance for the cam lobes cause I like high lift cams. This is only my second TC build but have been doing my own work on everything from my 53 Panhead, through evos, and now TC so know some.

Thanks. Do you have any tips for someone doing this for the first time? Most I've done is apes. The more research I do the more confused I get. Especially with clearances and gasket heights and cam swimming.
