Getting ready to install a set of Jay's new heads "Absolute Speed"! They will have the dual springs 977 that way there will be no questions of valve float with new rockers. They are cut .030 and the current cam is a :
cc 224-228 / 563-569 / 112 and I do run a 100-150 shot as well. What is the biggest cam without fly cutting the pistons that will fit? If I have to cut the pistons then I'll just do the entire bottom end ..... All mods in sig..

Thanks
