Having trouble with Heads and Cam
Having trouble with Heads and Cam So I am running milled 59cc AFR 205's with a TSP 224R cam, and it has been running great
But now I want to go with a bigger cam, and I was told by LGM that their G5X4 cam would not fit without flycutting my pistons, something I dont want to do, and he also said that their G5X3 cam would be a close one between the pistons and valves...
I was wondering if anyone was running these heads with either the X3, MS3 or any other big cam... Also if anyone had any ideas to what would be a good custom grind cam, that would fit...

While the X4 specs aren't anywhere to be found, I've heard its a lot bigger than the X3. I've also read posts by Louis @ LGM where he stated that the X3 does clear with AFR 205's milled to 59cc.
If you want the lowest chance of a PTV problem (specifically, having to remove for cutting valve reliefs), get the X3 on a 114 LSA. Wider LSA's usually leave more clearance. Aside from that, get an adjustable timimg set to move the clearance to your advantage.
Most people will tell you that flycutting is not the big deal its sometimes made out to be, and that running the cam you want, where you want, will be worth it.

hey buddy im building a heads and cam set up very close to your but my AFRs have a 62 cc chanber with a 224 cam. Could you tell me what kind of power your car made in hp and torque to see what I should expect out of my set up.
Thanks if you can help out

Regorih383, I made 410/389 with a horrible exhaust system... my tuner said I had at least 20 rwhp tied up in the exhaust itself...
- Maybe the 114 X3 is the way to go, I'm a stubborn young gun who wants the lope of a 112, but I guess I have to do what's best... By the way, if I were to pull my pistons myself how much would it cost to fly cut them anyways?

You don't need to pull the pistons out of the block. They can be done while in the block and in the car. I too would like to know how much it would cost to flycut valve reliefs.

my exhuast is a mess... but I probably would have made better power without the cutout open (my tuner said)...

Rob it can be done with the pistons in the block but i read the whole sticky on it and like i said major PITA. We would have to pull the motor then the heads and ruin your stock heads.
well I pm'ed PredatorZ, PatrickG, and Tony Mamo...
I got one response from PredatorZ who said a Custom Grind 231/240 .643/.609 on a 112+4lsa would be the way to go, I wouldnt need to fly cut the pistons and he says my stock internals won't crap out on me...

What size gasket you runnin?
I have milled 59cc dart 205s, which are pretty similair to the AFR's.. I am also running the X3 cam with a .040" gasket. I notched my pistons .080" for clearance as it was suggested from LGM and have not had any problems. Also, been sprayin the car ever since without any issues.
Also, the X3 is a 234/242 with like a 601/610 lift.

Why dont you want to flycut the pistons? Its a fairly easy process even with the motor in the block. you just have to find a shop that has the tools or one that will rent them to you. IIRC, LG motorsports does this.
