as long as your head inst milled and block isnt decked, run a stock 3 layer headgasket and run stock cam gears you will be fine

as answered in other post.


Good luck on your project.

 

Thanks irev210 appreciate it

seriously, just go dyno your engine.

THis thread has nothing to do with your engine setup, why are you posting it here?

I know what youre saying. That same guy came into my own thread and posted that same exact post down to the last "." Now seriosly! SI_In_Disguise go get your own thread and ask someone or just get your motor done and find out for yourself. Geez! Go check my thread https://honda-tech.com/zerothread?id=1162145 (under my friends account) and you can see he did the same thing there and if you have the knowlege to answer any of my questions in there-please feel free.
