I am looking for the BEST h/c combo. The block is a 2000 ls1 with all lower internals stock. Will be mated to a th400, in a 3000lb vehicle. I want the BIGEST cam that can be used with the stock pistons without cutting. Emissions are not a problem, the motor will be in an offroad application. The rpm should be somewhere between 1500-6000. I want a heavy/rough, lots of lobe idle. Now I need heads to flow good with a suggested cam. I need to keep about 10.5:1 on the compression (pump gas).

Can someone please suggest the best h/c combo with all the specs listed. I will need to know int/exh, lift and lsa of the cam. I want to know the head cc, valve sizes, what springs and retainers.

Thank you, Joey

Read up. There's always information you can find to answer your questions. You just have to look for it.

 

stage II ls6 heads can support tons of cam and a mild bore. Probably the best on the market, in my opinion-- then again I use them, so I'm a tad biased.
