I have a Lunati 230/237 .544/.543 112. I can get my hands on a set of 6.0l stage 2 heads for very cheap. They flow 295 at only .550. Milled .030 I think? Supposed to give me @ 10.8 compression. With the fairly small lift of the cam and the midlift flow #'s, I think this setup would make some great midrange power and be killer on the street. I don't want to wind the motor to the moon. Just wondering what the experts think before I go for it. Thanks!

I think it would make a good combination,some will say the cam needs more lift or less ex. duration but with a head that has good low to mid lift(also fairly good high lift)IT will pull hard even with the lower lift.You didn"t post your ex. flow #"s maybe they are a little low? If so the extra duration on the ex. side will help.You didn"t say what size motor you are running I guess a 5.7,are you sure of the CR,sounds high to me!A 6.0 head has a 72 cc chamber and a 5.7 has a 68 so the 6.0 would be lower,unless its been milled,about .4 to .5 lower.

Thanks for the reply. Yeah, with these heads I think a little more lift would help, but not enough to make it worth spending bucks on a different cam. Alot of lift (.600+)would be kind of a waste I think. Plus it's nice to not stress the springs much. I need to check again to see how much they are milled, I was told I would have 10.8 compression on a 346. I'm going to look at them this weekend and check out the flow chart. What would decent exhaust #'s be, keeping in mind that they aren't big name heads?

with 6.0 heads milled .030 you'll be at stock compression, assuming you use a stock .054 gasket.

The heads are milled .030 with 63.5cc chambers. Do these numbers look good for my cam and stock cubes?

if the heads have been a 63.5 cc chamber then they've been milled ~.053 not .030. whats the int/exh port size and the full flow numbers?

I don't know the rest of the numbers yet. I couldn't look at them today, will probably check them out tomorrow. .030 and 63.5cc is what he told me. If they are .053 would they still be okay? I have to run 93 octane and can't flycut the pistons. What port size and flow #'s should I be looking for generally?

find out exactly how much they have been milled, have them checked if your in any doubt or clay your setup to see how much clearance you have. check tea, absolute, and pp websites. they all have flow numbers to guage by.

You could cc the heads yourself, all you need is rubbing(green)alcohol a clear flat piece of plastic and something to measure the alcohol in.flow on ex, should be 230 to 250 or so,you could run your CR pretty high with that big of cam as it will bleed off low speed cylinder pressure.Good idea to check valve to piston clearance with some clay too!
