So is the gasket a newer revison of the 2007 oem unit ? part #s please? PTP John should not be discounted. They did some interesting stuff. And built some very fast cars even though the specialty was srt 4's i believe. lots of concepts are transferable.
I have a couple of the parts still I bought years ago such as windage tray and phenolic gaskets. Not installed though. still haven't pulled the motor and rebuilt , but it's on my list. So anything i can learn from others with experience is extremely helpful.
May i pm you about some details on the head and valve work ?
I look forward to the day when i can detail the plan for the motor build as you and some other helpful folks have.
good luck with the build !
I'm not upgrading the valves or anything, just having the stem seals replaced, having the head cleaned and deck surfaced. I'm not sure the part number but I'd assume it's the same as the new ms3 headgasket (genpoo) onlinemazdaparts.com could help you. I did BSD in September with the drop in build and also did the windage tray.
