My head and block where milled alittle bit (B18c1) dont know exactly how much, but im about to by a Cometic Headgasket but im not sure what thickness i should get, i have 82mm mid comp Endyn roller waves, and im gonna be running Pro2s for the cams.


Any suggestions or if someone can point me in the right direction thanks in advance.

 

I'm not trying to be difficult, but here's your question asked another way:

My feet grew a little, I don't know exactly how much but I want to buy a pair of shoes and am not sure what size I should get. I have medium sized socks and am going to be running the 400m sprint. Anyone know what size shoes I'm going to need?

Now in all fairness, how could anyone who's not psychic, answer your question?


If the block and head isn't milled much, I'd go with a .040" thick gasket and you should be close to stock height, but only you have the power to find that out.

 

Sorry for being vague, thanks for you input.

 

Is there any way for you to calculate your compression with different HG's?

The block being milled might be hard to measure, but cant you cc the head?

Yes, this would help but essentially your equation would still look like this:

compression = known value + ?

 

well...assuming that you had everything apart for your build measure out your head height and block deck height with you std. mic.'s and see what you come up with then compare to a honda service manual(or net database) and see where your numbers lie??...then come back to this question

but I'm guessing everything already to rock

hopefully i offered some assistance

Yea but it will give him a better guesstimate, no?

well no, because 2 + 2 = 4 right. What does 2 + ? = ...

CC' ing the head will give him a number but depending on how many valve jobs the head had, casting variations etc, you can't be sure how to translate the CC amount into head milling.

I suppose if you were somehow able to roughly see how deep the pistons sat in the hole (assuming you had stock pistons) and figured out your head cc's, you could probably be very close to calculating an accurate compression ratio.

 

Well you have the head cc'd, so you know that. Then you take mins and max deck heights and get yourself a ball park.
