Manifold swap?

will a 96 HO fit my 90? (by luck)!

I believe the 2686 head has intake ports that are larger(like 1/4" more on the low side), so you can't just throw on a HO or 99+ manifold, cause it won't seal. Now if you wanted to swap over a 7120(91-95) or 0630(96-99) head, it would work fine.

and those stock mani's are actually larger anyhow than my stock 90-4.0? but will fit all the same? wait- just read your reply 3 times and it finally pushed past the grease, HHAAA
