Most go with 62cc like mine... (.024 mill). I just installed a set of 59cc from LG with there G5X3 cam for a friend.
-Are you willing to fly-cut your pistons???
-Do have easy access to 93 (or better) octane gas???

LG used to sell/recommend a 59cc AFR head w/the GX3. You obviously would have to flycut in that instance.
The thing is you really should mill (and flycut unfortunately) for the additional compression a cam that big needs.
Mark I am going to Lapeer tomorrow.

LG says they have a 66cc AFR head ready to bolt on, no flycutting necessary, no other modifications necessary other than tuning, I'll have to think about this over the weekend, they say I would gain about 40 more rwhp, that would put me at 422rwhp..total cost with gaskets etc. $2,700.00..

I'd double or triple check that. That cam will work with a stock head. The AFR head has a bigger valve. I really doubt that would clear.
What's $2700? Just the heads and gaskets? That's too much.

I assume that price includes, at the very least, AFR 205 heads, on sale at Texas Speed now for $2000 plus s/h, rods, gaskets, install and tune.
Is that really too much to expect to pay ?

...if, the $2700 includes s/h, rods, gaskets, install and tune, then IMHO the price is very reasonable.

The AFR 205s are not inexpensive, to say the least. I've seen them anywhere from $2000-$2500, w/o the 921 Dual Springs & needed associated parts.
