Guys, im going to be taking the motor back down here before long for a set of ported heads with comp releases, and I have been trying to decide on which cam to go with that will meet me in the middle with every day rideability/reliability, and performance. I typically like to ride low-mid range, some two up, and mostly in town, less than 70mph, so I think the woods 7H will be a good choice. Should make good power down the mid range. I'll be using a .030 headgasket, may even have the heads milled down a bit for a bit more compression. I am planning on being able to use the stock springs and pushrods also, anyone have a problem with that? Does this setup sound good to you guys?

 

If you don't ride with ear plugs, get some.

 

Lot of valve train noise?

 

I can't say so with certainty on that particular cam but I have ridden with some that run Woods cams and the ones I have heard, excepting the 5-6 and the 6, were noisy. But, noise is a pretty subjective issue; noise to one is music to another. If you do run his cams, run the directional lifters as well.

 

I'd lean in the direction of a 777, with the gasket, and re-surface to establish 10.35.

scott, what If I dont have the head surfaced, just use that gasket, would you use the 7h?

 

Well, looking at the bigboyz calculator, .030 gasket, stock heads volume (86 cc) and flat top pistons = just over 10:1. With the 40 degree intake close, that's 9.25 corrected. Looks good to me, but I know Scott likes to run them higher. Other builders like to keep CCR below 9.3.

 

Yeah, and thats right about where I thought I'd like it to be. I don't want to have to give up my reliable bike just to go a little faster. Do you guys think I'll be safe with the stock springs and push rods?

 

TW-7H is only .575" and is advertised as "bolt-in", which means to me stock springs are good to go.

With my build I installed the SE adjustable push rods.

 

OEM spring will accept that 7H, but I'd lean in the direction of a set of adjustable pushrods, in order to load the lifter .140-.150" to help establish quiet operation of those cams.
