Hey I was wondering if anyone out there has cleaned a head thoroughly before installation? What are the best products to use for carbon and oil? What degreasers have worked the best?

 

No one has any idea?

 

brass wire wheel fro carbon..........and i use purple power for degreasing, works great for me.

 

Final Impact....Question for you. On the bottom of the head I got, some of the valves are carboned up, but some are yellowish looking. What causes this? Every other head I have seen has carbon on all the valves!!

 

carburator cleaner does wonders but so does any degreaser material like zep, purple power, etc

 

engine degreaser+carb cleaner+whatever Nissan uses in their mechanical scrubber=

that looks just like my cylinder head except mine is fully dessasembled ready for a port and polish. Did you do anything with the valves, springs, retainers etc?

 

no, the head has low milage on it, so i dident mess with it, just cleand up the CC a little bit
