i have a d16a6 block and i can get a d16a1 head for almost pennies. the plan is to use a block guard and put new eagle rods and eagle crank and new cnc macined pistons and turbo it. what to i have to do to make the head and block to mate, by the way this is going into a 88awdrt wagon thats why i am sticking to the dseries. and possily i might get adjustable cam gears but that is not a for sure thing.

Thnak s for your help

 

One head bolt hole need to be moved and make head gasket bolt holes bigger. I tried this but vise versa d16a1 block sohc head and was to much work for me let me know how it turns out for you

 

d16z6 or d16y8 head would be a lot easier.
