"short deck" 351w question

I bought a 70 model 351w to build for my Fairlane. Doing some research I find this has the .020 shorter deck than other years. Is there going to be an issue for me? Do they make piston sets for this issue? It's a virgin block, so it shouldn't have been cut once already..
Any thoughts?

Nothing fancy and pump gas friendly for a 67 Fairlane.
357 (no stroker) Stock crank, eagle SIR rods, forged pistons (flat top-considering the new Keith Black Forged ones) Will probably start with GT40 heads and go to AFR185's later. Mild cam. Performer RPM..

Then you have no issues to worry about, standard run of the mill build.

THANKS. Guessing It will have just a bit more compression? Should I take this into consideration when buying the heads or is it not enough to worry about?

Re: "short deck" 351w question

I think your lower deck height will make your combustion space about 4 cc smaller, all else equal. So your compression ratio will be about .4 higher, again all else equal.

Re: "short deck" 351w question

For a stock build There are oem replacement pistons that were used in the 1969 351W four barrel. They are flat tops with four eye brow valve reliefs. They will give you 10:1 compression with the early heads. You can get a better than stock cam with a smooth idle that will improve milage and power band.
