since i am going with a turbo and i will have the 6.0 apart i figure i will do a nice cleaning on the heads. anyone ever try and polish a chamber? seems like a little deburing or polishing or something wouldn't hurt while i have it apart. anyone ever do anything like that? is there too much casting material to really get it smooth?

Cross-Buffs from Standard Abrasives are the BEST way to polish a combustion chamber, use a rotary grinding stone to smooth out the spark-plug boss and then polish the hell out of them with the Cross-Buffs

I did on my 650CC ATV. Its not hard. Just dont sit in one spot to cause a dimple. Stay moving around and you really cant mess it up.

i have a dremel and a die grinder, not sure what this stone or cross buff thing is your talking about. could you be a little more spacific.

I'd invest in a good valve job,the polishing will make you feel better but a good valve job will yield big horsepower benefits when you add the turbo.

i need to go ultra budget, save my bucks for the 409 and afr heads. just trying to get by for a few months is all

and see how fast i can run on a pieced together 6.0 with alot of miles before it blows

Parish,I don't think the AFR heads are going to give you any more power with the turbo than ported 6.0 heads and a forged piston 6.0 engine will probably make more effecient use of the turbo size in your kit.Just spin the motor a little higher with a little higher boost.

Polishing will help with detonation. There are some serious casting bumps on these heads which would make them prone to heat spots. I am in the process of porting my own 6.0 heads (just put the grinder down less than 2 hours ago) and I am planning on polishing mine. I have little patience so I don't know if I will ever achieve a mirror finish, but anything will be better than stco.

a set of ported 6.0 heads with springs and a good valve job aren't going to be all that much cheaper than the afr heads i dont think and the afr heads have an extra thick deck wich should be a really good thing for a FI set up. seems like the afr heads are listed under 2k complete with no exchange. then sell the 6.0 heads for a few bucks.

there are so many ways i can go with this i just dont know for sure what to do.
