Thanks,I have a pile of Dyno sheets that came with Dave's hot wheels car.from 600 to 767. Supposed to be from the w2 r3 small block that came with the car. I'm kinda new to w2 heads. But 767 seems like alot for.thoses.heads

767 is going to be a pie in the sky number. Well prepped heads can easily make 630-640. After that, any power you get comes with a ton of work.
