Sorry it took me so long to get back, being an OTR driver, I don't get home much, and when I do it's brief. What have you done? To answer your question about having the heads machined for larger valves... yeah, you can do that. BUT for the same cost range you can pick up the Roush 180 or 200 heads. I choose the 180 because the head chambers where smaller giving a higher compresion ratio.
