I mated a d16 head on a d15 block but im getting no combustion. i have spark and fuel. Please help

 

Check your compression

 

Is your timing correct?

 

my compression is on point according to my freind. ill tell exactly how much it was but i wasnt there when he tested it, and my timing is perfect, TDC, head and distributor are all lined up. I did a search and noticed that someone wrote that the d15 and d16 are the same. The only diferrence is that the d16 has a wilder cam. Can i just put the d16 cam in the d15 head?

 

Anybody! Please I need help bad. Any advice?

 

Pull Plug 1 and put long screwdriver in it make sure piston is at TDC. I forgot my pully key once and my mark was way off =P even thou everything lined up.

 

ill try that, but today i noticed a really small gap betwen the intake manifold and the head. im pretty sure thats the problem. (That could be the problem, right?)

 

its my head gasket, theres oil all the place, plugs are soaked. thanks for all your helps guys
