Hello ,advise tips required please.
iam running a 3.5 ltr and have removed the heads for a decoke my plan is to fit a composite head gasket <real steel> and replace the heads with a nice pair of 4.6 heads.my question is what will be the new compression ratio?
cheers kev......

I reckon the compression ratio will be as it was before. As stamped on the block by the dipstick.

4.6 heads plus comp gasket will be the same as early heads with a tin gasket.

If you don't torque the outher row off bolts to full torque, you can use the standerd gaskets without problems.

I rebuilded my engine years ago, lots off pulling and offroading since then.

No probs
