Latrer model 12v head on VE truck

[RSWORDS]

Anything special I would need to do? Can get a good deal on a 95 12v head. I know it will bolt up but is anything else different? Injector threads in the head the same size?

As far as I'm aware, a 12v head is a 12v head- it should bolt up just fine. The injector bodies are different in the latter 12v heads, but the hold down nuts are the same.

The heads are dang near exact. The only difference is the spacing of the holes for the throttle linkage bracket. Not a big deal and can be worked around easily.

actually there are a few changes to the ports and the second gen head flows better

[Ramrod90]

I have heard that but just as many people have said that there was no proof to back it up.

i got a great buy on an early 98 12v that was rebuilt,then mixed oil and coolant. i took intake cover off that head,so i could see into valve bowl area. non i/c head and a 93 i/c head.the valve bowl area was alot more open on both the 98 and 93 head vs the old noni/c head, casting was smoother too. the difference between 93 and 98 wasnt much. i bolted the 98 right on my 90 block. it seems to flow better. replacing a non i/c head if you have a reason is worth it but they all seem capable of good power

The Non I/C heads are known to crack anyway, so you are better off replacing them.

If you replace a Non I/C head with a later head, then you'll need to buy new injectors since the reason the Non I/C heads are more prone to cracking is due to the larger holes for the injectors than the later heads.

What??? That is not true, All you have to do is go on PDR and get the 7mm to 9mm brass injector adapters.

No hes saying you can't put your non-ic injectors into a newer head because they are too big.

Yep, you can't put non I/C injectors into a newer head.
