You can use the 1.8 rockers and the lift will change to .593/588. I personally haven’t used 1.8 rockers so I can’t say the gains are worth it or not. Might be a little tougher on the rocker arms though. Hotrod has done a lot of Dino tests with Ls setups. You could probably find great info there. LS1 tech will also have a ton of info as well.I want to make 400 at the wheel before turboing It. Any suggestions. And I was told I could use 1.8 rockers to help me with power.
You have a very good turbo setup as is. Most or your gains will come from tuning and heads.
If done correctly, heads are going to be an area you should look into. The pocket port work done underneath the valves is going to give you the most beneficial gains.
You can do intake and exhaust port work but I recommend just doing a mild casting cleanup or “machined finish” on the intake side and smooth (polished) Exhaust side.
There are really no power guarantees on any motor. Identical motors can be 30hp apart sometimes.
