L92 milling fly cutting questions
L92 milling fly cutting questions Ok, Ive done some searching and still have some questions. I got some L92 heads off of Bruce@Powrmax, and I want to have them milled to bump the compression on my Lq9 to about 11.0 to 1. I figure that .030 will get me about there. Im probly gonna run a TSP 231/236 cam with this set up. Would I be safe going with a .080 fly cut for both intake and exhaust valves? I know that oh of the vavles needs more clearence righ? Any help would be awsome, I know and plane on checking the clearences just looking for something to get me going in the right direction.
mock up the motor and check with a checking valve spring. I used an old fuel pump spring for my checker. then you'll know exactly how much to cut. that way you wont be going backwards by cutting too much, and reducing compression.
