7.400 pushrod length ok?
Doing an Lsa swap and heads had 15 thou taken off. Running LS7 lifters and BTR stage 3 cam kit and springs, with LS9 head gaskets. Wondering what people think?

Different than stock gaskets and milled heads?
If this was mine I would measure it. All that work, why chance it?

With all that work involved I wouldn’t want to roll the dice on rod length. I’m going with InFi on this one, I’d definitely measure.

Comp cams has a nice PR length tool. Pick a length that gives you about .070" depth.
The tool comes with good directions how to use it. If just a .005" clean up pass, could get by with stock length PRs. Taking .015" off I and diff gaskets, I would measure. |
