I gained 2whp for going to roller tips on 130lb springs. NO other changes! And another 11whp moving to 1.7 rr'*.
2whp?

Care to take a guess as to the normal variation from run to run on a Dyno?

I do have add that my 2whp gains was taking 8 runs. 4 prior, and 4 after on the same day. Taking the best times with each setup. With the RR'* there was actually less of a variance, all runs within 3-4whp.

ZZP has no idea what the LN3 even is. We can tell you with certainty that those rockers will NOT work on LN3 heads.

Time to swap the heads!

But oh well, it'll be worth it

Are the 93/94 L27 heads a direct swap to the previous 92'*?
