LA 318 advice

That's for a needed reason, not just cause you don't want to run proper pistons.

This is a general build, say the dude ends up wanting to try a few different intakes now he's got to mill each one and are pretty much useless to anyone to use after.

I’m Just saying it might limit any future upgrade, now if there's zero chance for any possible upgrades then fine mill the **** out of it. But you might think there's gonna be zero chance then life happens now where trying to figure how to use this short block in a new project.

With no valve relief's ?

Yes I'm not an engine builder, everything I've done been to a stock short blocks.

WTF are you talking about? What is a “proper” piston?

You can stack gaskets if you change blocks. This **** isn’t as hard as you want it to be.

It doesn’t limit anything unless you limit it.

How many times have you checked p/v clearance with an off the shelf piston?

Do you know how much that clearance you actually need and why more clearance is bad? And why?

It’s for the same reason you see some unlimited class stuff with very wide LSA’s. They don’t do that because the wide LSA makes more power because it doesn’t.
