Recommended head gasket kit?

[willxfs]

Looking to change out my head gaskets and intake gaskets. Which is the better kit.

1. Felpro Permadry kit

or

2. Felpro Perma Torque Severe Duty

or any other recommendations.

Anything else to look at while I have the topside opened up?

use the fel pro hst7733pt16 kit the Perma Torque Severe Duty one. better head and intake gaskets and valve seals.

also replace the original efi design with a new Delphi FJ10566 Fuel Injector SCPI to MFI Conversion Assembly

you will also need two of these head bolt sets Fel-Pro ES72856 Misc Set and one set of Fel-Pro ES72224 Engine Intake Manifold Bolt Set

inspect and if needed replace your dizzy gear. have your heads inspected as well as definitely get your intake manifold cleaned and blasted at a machine shop it is going to be dirty when you see it.

if there are no defects with the cast parts and everything is assembled properly you will not have any issues at all with leaks.

Thanks for the information Sunlit. Almost forgot about the new bolts. Definitely need those. Already have a new spider injector set so I'm good there.

I would like to clean up the bolt holes for the heads bolts. Anyone know what size thread chaser tool I need. Thanks

MLS is the best.

uh yeah, not needed for the application use here. we are not at the track on a continuous basis to justify it. besides the printoseal has fantastic sealing abilities and cylinder armor is more then enough for some great modding of engine for power.

would this be a good one? seen several injectors but really just wanted to know if this is a better than decent choice.
