Dont waste your money. Just get an OEM gasket.

if you ever over rev on a downshift or god forbid miss shift, I'd rather have a few more thousandths of clearance :D

I believe the spoon gasket is a modified oem gasket with the middle layer removed,

.3 to .4 bump in compression is not going to make much of a difference in power

just wondering do ppl pull the rivets out and make their own thin headgaskets with K headgaskets like they did with B?

I did that with my Bseries and just ran a signal layer headgasket and so far it's holding up no problems.

But K, i'm not sure if it'd work the same?

Also, something that may or may not be an issue is if you run a thinner head gasket, it's going to lower the head a tad causing the timing chain to need a bit more tension, also slightly altering timing. Now, a thinner head gasket may not be cause for concern by itself but combine that with normal chain stretch (or excessive chain stretch in some cases), and possibly a milled head or something and it may be enough to throw it off. The timing chain setup on these motors is quite sensitive, as we've seen in the past.

With all of the issues with chain tensioners and ruined engines that some people have experienced, I'd personally try to do all I could to avoid that and running an oem sized head gasket just seems safer to me. Something to think about. :up:
