Looks like I might be getting some roller rockers since it'll probably be in the budget.

Just read up on break in procedure for a high lift cam and I read that it was recommended to lower the spring pressure back to stock or lower the rocker ratio a good bit for break in if open pressure is 260+ lbs which I'd imagine it will be. So since tom's kit's valves looked like a 2 piece valve, I'd need to remove the inner spring, then break it in, then find a way to remove the retainer and put the inner spring back in while the head is still on?

I looked the turbo up again. I didn't see a max psi. Just an intended hp range of 350-550hp.
