Hi guys, there is 220 thou of valve drop with a milled, 59cc AFR and .040 cometics.
There is 200 thou of valve drop on a stock motor.
Any X series( G5, X1, X2, X3, X4, 111/112/114 excluding the xX ( which in most cases, thats install only here at the shop) will fit on a stock engine, 112 or 114. The X3 110 will not clear stock heads, but it will be close on the AFRs. You gain quite a bit of PTV with AFRs. If you are not sure, and want to know what your setup came in at, check it.
Let me know if I missed any questions, Ill keep an eye on this thread just in case

So the AFR 205's will work with the G5X3 on a 112 right out the box without any flycutting....While we're on this subject, have there been any other heads that have worked well with this cam, im basically wanting a good set of heads to work with the cam without having to do any flycutting

I have never touched my motor before, so assuming that I go with upgraded springs and pushrods, I will be absolutely fine with a G5X3 on a 112? Absolutely fine meaning it will require no flycutting and there will be no damage done to the motor.
I will be using this cam (if possible) with intentions of running it cam only for quite some time, and then stepping up to some AFR 205cc heads. I can do that with no issues, correct? What size chamber would be optimum for my intentions?

No flycutting on stock heads, or the AFRs. If you pick a set of stock castings that are ported and milled with big valves, that will NOT work. AFRs only. ETs or Patriots, darts, ect- like I said, Im not sure. ET makes a good head, I just have not had any of their stuff on my dyno yet.

I am running AFR 205 milled to 60cc and a G5X2 @ 112. I am running a .045 gasket.
I like the G5X3 @ 112 as all of LG's cams make good power.
Louis - Just checking, but I thought that the AFR 205 heads would need to be flycut with a G5X3 @ 112? I know a bunch of guys that needed to flycut. Now I am thinking maybe they did not have to do it, but just did to make sure.
Please advise as I may get a G5X3 @ 112.

Yessir, no issues what so ever.
The 59cc AFRs with .040 cometics work very well. I have may dyno sheets up in our gallery at www.LGMotorsports.com that you can look at. Most are labeled![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

No flycutting necessary with AFRs at either 59 or 60 cc, or anything larger, say 61-72cc. The X3-112 will fit just fine ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Many people flycut for 2 reasons- more clearance, and the slim chance they may want to go with a larger cam down the road, and do not want to pull the heads back off to flycut![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

I bought a x3 and had tsp do a cnc on my heads and install 2.04 intake valves and
I have yet to dyno the car(02 z06),BUT it's definetly the way to go I don't know about
clearances but it will turn up and pull like a beast.The sound is simply amazing with longtubes and no cats with b b bullets.No regrets at all.

AFR 59cc chamber/.040 Cometic/G5X3/114lsa
what are we looking at(ballpark) as far as clearances are concerned.....
I think the rule of thumb is .080 exhaust/ .100 intake???

Doug- We flycut the majority of our installs for a few reasons even though it isnt necessary. They will clear fine, but you have to remember, the volume of work we do, we have to idiot-proof the installs so the customer can bang the 3-2 miss-shift and not tap any valves at 8500
. If we didnt, that one customer would bend a valve or 8. Most people never have that issue, and the DIY Guy doing stuff at home knows what he is working on.
I will never turn anyone away from flycutting, and lets keep in mind that most of the time its necessary, just not with the combos everyone is asking about![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Wavrdr- this is a very common combo as you probably know. Rule of thumb is .055-.060 min. on the intake (thats close), and 80-100 on the exhaust. The more the merrier. With that setup (X3/114, 59cc AFRs and cometics) You are looking at ~ 80I/130E. Everyones setup will vary, but thats been the number.
