Ok guys I just have a few questions.

First off, i'm planning on making a 350hp build and i'm not sure if i need an upgraded fuel pressure regulator. do I?

Secondly, do i need a metal headgasket even though the head has never been taken off? Shouldn't the stock headgasket be good enough for my setup as long as the head has never been taken off? meaning that the original seal is strong and everything is tight and formed whithin the grooves.

Thirdly, Should i install an oil catch can? I've heard that higher blowby pressures can cause oil to make its way into the intake manifold through the T-connector.

Any advice is helpful thanks!

Sr stock has a catch can.

Adjustable FPR helps with tuning. You don't need one really, just make sure you upgrade to a higher output fuel pump.

Leave the HG stock until something happens to it.
