Bore size and valve reliefs

[evil66]

Im not sure if anyone has put the new edelbrock victors on a factory block yet but does anyone know what size bore would be required as a minimum without having to notch got clearancrwith the 2.15 intake valve.

Also would custom pistons be required with the 16 degree valve angle.

I would think that the cam lift, duration, and piston compression height would be more of an influence on piston to valve clearance than bore diameter...

Put it together and use some clay to check the clearance...

Thanks, i havent bought the heads yet but wondering if it is worth doing with a standard 360 block and if 30thou over is enough or if i will need to have a bigger bore
