Hello all,
Anyone share experience for Ferrea and Supertech valve products?
Do I must be replaced Ferrea valve guide with Ferrea valve? Or May I use with Supertech valve with OEM/ Ferrea valve guide?

Sorry for I dun have any experience for valve guide replacement.

Thanks!

 

I’d contact Ferrea and ask them for suggestions.

 

you can mix and match them however you want. both are made very well. The only that matters is clearances. And the guides always need to be reamed to the correct diameter for proper clearance.
Personally I prefer supertech for all parts, because they cost less, and I've never had any issues with them.
