hello, its been a few years since ive been on this forum, but im back into building my lude finally and decided to build a turbo monster. I have my bottom end built and my goal is to get around 600-700hp high boost. I am probably going to use stock cams for now or maybe skunk2 stage 2 turbo cams but im trying to figure a size for the valves. my bore is already over bored to 89mm so i wanted to get oversized valves. Is bigger always better in this application? can I get 1mm oversize without losing a ton of low end?

700whp lude? wow....i hope you don't think it'll be a daily driver

nope, but it could be on low boost. this motor is pretty bulletproof there is a lot of money into it and its blueprinted. but if anyone has made this kind of power let me know what your head set up is and how it worked, i am able to machine just about anything to get it to work well. do i need to replace valve seats for larger valves if so where can i buy them?
