Fitting standard 4.6 heads to a Thor?

stopover · Jun 16, 2012

Anyone see any problems fitting (perhaps) standard 4.6 reconditioned heads to a Thor 2000 engine?

The recon heads I have are casting number HRC2479 are these pre 99 or 99 on?

your will have no problems mate, will go straight on, but why not ask your local machine shop to open up the valve throats a bit and 3 angle cut the seats - will gain a theoretical 20 Hp min at a small cost - while they are off etc

Good thinking, will do as you say.
Thanks
