I wouldn't think the drag would be really any different than swapping in a slightly bigger cam??Adding 1.6 you are also putting more drag on your timing chain and all components in between.

Disagreed! I think your air cleaner is cool as hell...huh...??? I was answering AndyF about 1.6's being a help to my combo.
But to answer your remark about my engine, my crank, rods, pistons, heads, valves, ports, pushrods, and rockers are all stock or OEM replacements. And a factory cast intake/TQ would work as well as my intake/carb for performance. Oh, you didn't mention the gaskets, paint or plug wires, they aren't factory bone stock either! Air cleaner? LOL... Pure Doofus.
I'm sure you've figured the reason for this thread. I'm trying to calculate exactly what I am to expect by going to the mag heads. I'll gain slightly bigger valves, better flowing ports/bowls, a bump in compression, better valve springs, and.... and 1.6 rockers. I can guess the rest of the list, but not the 1.6. Thus the reason for this thread. Then I'll use my best guess and see if they make me happy or disappoint me.Disagreed! I think your air cleaner is cool as hell...
Well why beat around the bush, why didn't you say that the first time... Also, COOL!....I'm sure you've figured the reason for this thread.

Why? That's easy! I didn't want the conversation to be about "magnum heads" and all the pro's and con's, or the 1.7 Harland Sharpe roller rockers that I have and could use on the mag heads. Nope! I wanted it to be strictly about 1.6 rockers. So far we've had 3 pages of good info. Now, SHhhhhhhhh..... lets forget the magnum heads and get back to 1.5 vs 1.6 rockers.......Well why beat around the bush, why didn't you say that the first time... Also, COOL!....
mag - work with factory valve trainR ur 1.7 rockers mag or LA?
Because the ratio is 1.6 to 1 it will be harder to push than a 1 to 1.5 ratio. It is simple leverage. a 1 to 2 lever is going to be twice as hard to push but travel twice as far as a 1 to 1 lever.How so?
I was going to disagree but that would be going overboard....you posted nothing ?? lol
It would be harder on the pushrods? Maybe the lifters? Can't be the springs or valves. But heavier springs and bigger cam would be harder on the push rods/lifters than going to 1.6 in my way of thinking.Because the ratio is 1.6 to 1 it will be harder to push than a 1 to 1.5 ratio.

Thats why.
also even if the valves move the same with a bigger cam the higher ratio is still harder on the system.
Yea I have read alot of bad about "budget" roller rockers. I havent seen any other than those 179 dollar ones on ebay that's "affordable" and they have terrible reviews for the money I'd love to see some real world results like 318willun.Having gone through a few sets and ended up with HS rockers that get adjusted once a year, I would HIGHLY recommend not putting your rockers on a budget.

Yea those do look crappy. Looks like they where drilled out and never finished.View attachment 1715402667
I bought a set of those cheap rockers and even my tight *** sent them back the same day.. the Machining was almost non-existent and quality seems like total garbage... After I seen all the different rockers and all their imperfections there was no way I was going to take the chance...
Is that blue marker, paint, or actual anodizing?View attachment 1715402669 View attachment 1715402670
That last picture is showing the pin coming out of the roller..
