The guy running it hasnt flycut his pistons and hes been running it perfectly fine...
It was designed to be run without flycutting. I already talked to chummmma about this
btw the reason I dont want to flycut my pistons is because of the added cost of doing so.
If I am correct its a few hundred bucks to get a shop to flycut the pistons

I gained .2 just from swapping a Yank SS4000 for a Yank PE4400. So your car will enjoy a bigger converter.
It's hard for me to choose between Texas Speed and Thunder Racing since they are the 2 main places I buy my parts from, but I ended up choosing the TRex. I felt it was the safe choice to go with, and it was putting out great numbers. I was also deterred by the larger lift specs on the MS4, I felt it may lead to premature springs issues or the need to be changed sooner.

The MS4 will clear with enough PTV clearance so that flycutting won't be a concern. It has way more PTV than some of the other big cams out there. We have installed it on several cars using stock heads without an issue. Put it in our cam package with the PRC Dual Springs and chromoly pushrods and your valvetrain should be ready to go! If you have any questions at all, feel free to give us a call or shoot us a PM.

It's all about when and where the valve events occur. You could have a .550 lift cam hit the piston if it begins to open faster than the piston leaves TDC.
You want the valve to safely follow the piston.
