lt1 intake port size

[thirdtimevetteowner]

I need some help deciding on an lt1intake conversion on my 89 L98. The determining factor will be whether I would have to remove my 113's to gasket match, especially since these came off an engine that the heads were given a Stage 1 job to. How much bigger are the lt1 head ports compared to mine? Thanks for any help, as usual.

Anyone? Madmic? (I seem to remember you saying you were considering this same project). Then again, you have aftermarket heads, which I hope to have eventually also. Even Scott at lt1intakes.com couldn't say for sure, not knowing how much the Stage 1 port job opened up the ports. Anyone like to chime in? TIA

If we're talking stock '113s, the LT1 head is about 7cc larger in size, so its not a big deal.

Thanks Vader. What about the fact that they have received a Stage 1 port job? Still no big deal?
