Hi I was wondering if anyone is running this combo?I am getting ready to drop the 351w in my cobra it has edelbrock #60379 heads,1.7RR and a F303 cam and my pistons are TRWL2446F30,whice are dished pistons.I was wondering if I will have any valve to piston clearence problems?I have the motor all together and spun it over by hand and everything feels fine.Also will the springs be o.k on the edelbrock performer heads?I heard they will be fine to a .575 lift.If I did my math right I am going to be at .544.I guess it is a little late in the game since the motor is together but I just thought about this.Thanks in advance for the help.Bill
