Only thing I would suggest is the 241 over the 853. Perimeter bolt valve covers look hideous. If you have vc's and coil brackets for either than it doesnt really matter. They will make the same power in the end. If you were to re sell them in the future though the 241 would look more appealing to someone that would want nothing to do with the 853 because they just know its the older model.

Verdad Gallardo Ha! Yes, you're right! Then again. No difference with the 853/241's. Porting would change any small thing that may have been altered btwn the 2 anyway. It could be a simple water jacket route that was different that wouldnt affect flow. I'm not really sure.

thats a good point, i guess the ports are where they are and i didnt think for some reason that a cnc port job is going to make the ports the same no matter what head. good call sir.
I dont know what the heck I was thinking with the 853's. You clearly said 99 camaro. That should have been a dead giveaway.

dont feel bad, i havent driven my car in over a year, im losing my instant recall on things i should know about them as well. i think the less i drive my car, the less things to go wrong that i have to think about and refresh my memory.

ok, i was looking at the heads again. is there any difference in the valves between the two? or should there be anyways? i noticed in the 853 heads, the exhaust valve has a pretty good dish to it, where as on the 241 heads, it is flat. i know this will give me a little more compression, but should there be a difference in valves or did someone change them to something else? what would they be?
here are some pics i snapped.
