Stroker 340>416 Build Advice

Some people have no interest in porting a head, I don't want to do it anymore either when I can get a cnc head for a few hundred bucks more. The mancini rocker package is $520, hardly exotic, and not much more than any other roller rocker arm. You do not need a "radical cam" to take advantage of the trickflow heads anymore than ported speedmasters, they flow quite well at low lifts and are not "race heads". Some people want to spend more and get better quality parts and some are on a tighter budget and shop around, its up to the op as to how he wants to spend his money and he asked for opinions which we all are giving. It's great you are offering alternatives but at the same time just need to deal in facts and not what's good for you lol.
Yes I think it's great we all have a different experiences and that's the great part about this forum... People like the OP can dip into all of our experience and formulate their own opinion on what their needs are and what their budget is...
Like on another post about ignition systems I've done factory and I've done full out MSD and didn't see much difference. I've done 273 rockers and switch to Hughes 1.6:1 rockers and didn't see much difference... I've switched from 3:55 gears to 410 gears and didn't see much difference lol... I'm switched from factory heads to aluminum heads and didn't see much difference... LOL..
With all of your experience and all of my experience mixed together I'm sure the OP will have plenty to ponder over...
