Default Head Gasket thickness/pushrod leangth

I currently have cometic .040 gaskets and am using 7.375" pushrods. I am wanting to go to GM MLS .054 compressed gaskets. Will this difference cause me to have to get longer pushrods?

What is the preload on your lifters now and what lifters are you using?

The only way to know 100% for sure is to measure the pushrod length by determining the preload. Generally, if you are within range, even after the gasket install, it would only affect the preload by .014. Usually not enough to warrant a change in pushrod length. It just depends on what end of the spectrum you are with your current lifter preload.
