I have a 350 that I will be upgrading. Im buying a Comp 503 cam, Patriot Aluminum heads (Pre assembled) 190/64cc with stealth ram air intake with a lt1 throttle body. New wires and plugs with cap and rotor with new timing chain. A/c delete and full exhaust. My question is will I have any clearance problems with the piston to valves with the new heads and what time I am expected to run.

Thanks.
