i know its been asked before but cant find it with no search function, so whats the minimum recommended thickness please, i think it was 138.6mm but cant remember

 

stu said this but ive seen them happily running at 138.4mm.

 

mines well over the limit and theres no det on my pistons

ive not had the bollocks to measure it though but i dont need to as even a gimp like me can see its too much

 

ginge, have you seen my post in pics and vids, i nearly have my bumper on whaddya reckon ya git big homosexual

 

Minimum thickness is 138.68mm

 

hmmm, mines 138.43 after this skim so a thicker ferriday headgasket is being ordered tomorrow

 

fen the thicker headgasket aint the normal idea

measure ya comp ratio before ya do anything and show stu the pistons ect before ya decide anything

btw the 3 door bumper looks cool, anychance of a side shot to comapre how mch further forward it now sits

 

doesnt matter at all what the thickness is...





as long as you're getting an engine built!

 

dave that dont make sence, if the head looses its squish areaand its not taking into consideration it will make alot of difference

if the engines being built and the ultra skimed head taking into consideration and other things looked at ( not spacer plates ) then it dont make a difference


providing when in take my pistons out there not fooked then im not gonna change mine at all or skim the head ( well i cant as the valves would open and show the engine bay ) as theres no det on my head at all and as i ideally need a new head im gonna stick this back together and fizx the problems i had with the engine and then im gonna buy a brand new head and have that sorted then rebuild it proper in the winter ( if i feel i need to )

any news when ya cars gonna have the engine fitted ect

 

i have seen na heads at 137 an they been fine
i also have seen a few turbo engine in the hi 137s and they have ran using machined pistons to gain corect comp ratio
it was a large port hear that cud not be thown away
in most cases if it s standard get another head

 

fukin is for me, ive spent all my money on bodge


it sticks out a little bit further than the std one but its a bigger bumper anyway so its ok, the front end looks as hard as fuck now matey, i am over the moon with it, i will prove all the doubters wrong , i will take a few more pics but you have seen the size of my garage , its not easy

 

ive just took a head of an escort cosworth that measures 138.1mm and it was running fine,the valves dont even look close to the edge.

 

tim you still got that bare head
if so count me in

 

i have,just put it on ebay but if you want it i will withdraw it and post it down to you.

same price

 

Ginge, you keep on going about detonation, as far as I can remember, stu told me that a head that had been skimmed too much would not have a significant effect on the compression ratio and wouldn't be something to worry about, the problem was that there was usually not enough metal around the valve seats ?:

 

pmsl @ Fen and the ferrrrrrrrymans head gasket

 

Read this

 

the squish area and valve seating are the issue but a well skimmed head can be made to still seat fine but ya still missing the squish area and a part on th head that creates hot patches and det

 

bastad im movin darn sarf as youre all rich fooka's, whats the matter with his gaskets like?

 

Fair point.
