Zach, shorter pushrods will not be the answer. I dont know how big the ms4 is and if you have a stock ls2 with 243 heads or what but the shorter pushrods are going to cause little to no preload on the lifters and it will be Very noisy. Maybe someone else can chime in on that cam though.

You will not have any problems with piston to valve clearance with the MS4 on stock heads. For those wanting the benefits of a CNC'd head with this camshaft, we recommend our Stage 1 heads which use stock valve sizes. This way you get the added power of the CNC porting and competition valve job, without the headache of fly-cutting pistons!

Let me know if you have any other questions about this or any of our other combos, and I'll be glad to help!
