These cylinder heads were ported this summer by Lloyd Elliott and had a valve job done as well. I have used these in my car for about 4,000 miles after the heads were ported. The heads are aluminum and will include 3/8" studs and the dual valvesprings. The springs are made by Combination Motorsports p/n CM618. The springs are rated to .600" lift, I am not sure of the specs on the seat pressures I can find out. Click on the link below for pictures, the other head is being removed from the car at the moment but here is the drivers side head
