Default 113 heads

swapping 113 heads into an 87 vert, will all stock parts work?
intake and exhaust manifolds especially.

Yes, they should fit with no issues. The 113 heads are Corvette heads.

when they refer to d port, isn't that the exhaust port, so i assumed it would need a d port exhaust manifold to line up

I put on 113 heads on my L83 (1984). Gross mismatch between manifolds and ports.

Yes, but now you're comparing two different engines.

still a little suprised that the exhaust manifolds are the same from the 2 different heads, I'm sure that there are other differences in the heads but why would the 87 manifolds have a d port flange, if the 87 heads are not d port
