Owner reviews for cylinder head

A second used head, this time from a 2017 model, was sourced and shipped for $600 ($500 for the head, $100 shipping) and was rebuilt by a head specialist. His bill was about $800 and included new exhaust valve guides, a valve job, milling/skimming the head, removing and replacing six oil plugs and thorough cleaning. Total cost for the rebuilt used head was $1,400, a relative bargain compared to the $4,000 VW wants for a bare new head.

after 2.5 months, my CX-9 is back from the shop with a new cylinder head!

The cross flow (ABA) has bigger ports, especially the intake side! I mean sided by side in my garage, instantly noticeably bigger, like it would take immense porting to get a PG to ABA size.

On the other hand, head was fully rebuilt. Previous owner(s) were probably changing oil every 50.000miles, with cheapest one available, which led to all sorts of gunk accumulating on valve guides, finally making it impossible for valves to shut completely. Resurfaced it, put in new valves, guides, seales... Set of gaskets and head bolts later, it fired up.

I have had a few 2.5 liter subaru heads rebuilt, 2 aba heads rebuilt, many flywheels machined, a few brake rotors machined, pontiac sunfire head rebuilt, toyota 4runner 3.0 liter heads, chev venture 3.4 heads, honda civic head. He is a perfectionist and does good work.

I had one, don't overheat it. The heads crack/warp easily. I went through two of them before I got rid of the car. just make sure the cooling system is good.

The 460 needs SVO heads minimum to even think about making any power.

Had the cylinder head crack on my 2020 Mazda6 2.5T at 50k miles back in 2023 which caused coolant to leak and overheat my vehicle.

My wife had a Sonata, she didn't take care of it very well. 10k oil change intervals, it blew the head, we replaced it.

I am really dissapointed with the 2.8 24v head
