I have been reading on PTV issues and wanted to double check in case I have been misled. I have a car that I am about to bolt heads onto:

Stock LQ4
Milled 62CC 241 heads (I believe a .020 mill)
XER281HR (232/234 595/598 113+3)

My question is, will I need to worry about fly cutting the pistons? I'm sure I can find out the hard way, but I'd rather not gather the remaining pieces only to find out my heads won't work on my short block.

I plan on possibly running nitrous and fly cutting is not an option for me, so it would be better for me to get a set of stock 243s if it will be an issue.

Thanks!

I would doubt it, but checking with clay is the only way to go.

you should be ok. Im running the same cam on a stock ls1 bottom end with 62cc dart heads with no ptv issues. So im going to say you will be just fine.

Theoretically, it'd be "better" to get 243's anyway since they're going to make a little more power than the 241's.

241's come with a 66.7cc, and milling every .006 is about ~1cc. So to achieve 62cc the heads have been cut ~.025-.028. It's gonna be close.
