This is probably one for Matra and the other more technical fellas here on UCP. I have a leaking head gasket. I have a replacement in my possesion, how do i fit it? very simple question, im assuming ill need to take the head off and stuff. do i need a new rocker cover gasket then too? do i need to replace hoses? whats the deal? as much info as possible or even a link to a site with a walkthrough would be heaps appreciated. heres just some general info about my engine:

Nissan L16 SOHC
1.6L NA
Headers are only engine mod right now.

ive had to have one done before after a blown head gasket and that cost me near 800 dollars to have fixed. the majority of the cost in labour. im feeling confident enough to do this myself now but i can always use extra help
