going from copper to OEM HG: how will this effect my tune?
I am about to switch from a copper headgasket to an OEM hadgeasket.
I am hondata tuned and was wondering how much this change in gasket thickness would effect my tune? I have no clue what thickness my current copper gasket is....
Also, should i spray the OEM HG with copper spray for a better seal or is that just a myth??

i wont know for sure until i pull the head and measure the current gasket thickness with a micrometer.
Would on be preferable to the other? (raise/lower)? My compression is currently 8.5:1....

im pretty sure a lower compression ratio (thicker gasket) will make your current tune run richer while a higher cr (thinner gasket) will lean you out some. someone correct me if im wrong

i think the compressed thickness of an OEM style FLEPRO gasket is 0.30in according to summitracing.com. So as long as my current headgasket is thinner than that i will be ok? (maybe a lil rich)
How mich thinner would the OEM HG have to be in respect to my current copper HG to lean me out to the point of detonation/problems?

pretty sure .030" is stock thickness. so maybe you are lucky and your tune wont be effected at all.
