G5X4 Cam, which Head AFR 205 or AFR 225, or TEA 2.5
hey whats up guys, i dont really know much internally about the LS1 , but i want to buy the G5X4 cam for my stock cubed 346ci. i want to do Heads alond with finishing off my bolt ons at the same time. 4 questions though, which Head do u recomend that works great with the g5x4 cam, Where can i get the G5X4 (I checked LGMOTORSPORTS.COM) but they dont have the g5x4. and last but not least what kinda power can i expect, AND Times with a 12 bolt, 4.10s, slicks and a good driver
Thanks

Give Lou a call over at LGMotorsports and he'll give you the rundown. That cam is kind of risky without flycutting your pistons. A missed shift could be devastating with that cam choice. To be safe, I would recommend the G5X2 because it is a bit safer on the clearance, and it makes awesome power.
As far as heads go, read the post AFR vs TEA below. There is input from both sponsors.

To make the kind of power you want I would go with the TEA 2.5. Right now you cant get the AFR 225 in the small chamber. With a stock bore you would need to mill alot to get the 11:1 compression ratio. The 205 is a great head, but shown that the BIG cams dont yield alot more power than the small cams due to the limited higher lift flow. To be realistic you cant go wrong with either. IMO would be the TEA.

LG has made 530-540 rwhp with AFR 205s with one of his bigger G5-X cams. I made 433 rwhp with AFR 205s and a 215 cam. Stay tuned to see what kind of power I make with a 231/234 cam and the same 205 heads.

Flycuting will be a must.
Both heads will get you some very nice gains.
Price is very simialr as well when you add in the TEA LS6 core charge. I would try and get into a 64cc head and a .040 gasket for 11:1+ compression if you plan on making some big power.
If this were my own car I would do a 59cc head with a .040 gasket and pick between TEA and AFR.
That would net you 11.8:1 and make some serious power.
Budget is the key.
If you have 2300 bucks to spend on heads do the AFR's in not then spend 1700 on a set of the 5.3's from TEA upgraded to stage 2.5's.
It's only a 600 dollar difference which is huge to some and very little to others.
