Integral Valve Guide (Broken Boss) Repair Options

I'd get on some of the forums for your kind of Truck
Mine would be gen 1 Dakota
find out what year computer you have and what it will put up with without a tune
Many HR's out there are meant for someone who has converted to carb (and headers)

What we had above was both giving the Lobe Centers LCA
both giving the durations at .006
one giving the intake centerline
which given the duration you can figure the timing
one giving the timing, from which you can figure the intake centerline
now you can compare timing- which is only thing that is important

Problem with Hughes is that they do not give you enough information to compare with anything else
any questions we can walk you through it
but it's like juggling three balls at the same time and keeping your eyes on all of them
you want the intake to close early with that low compression
but the computer wants a good vacuum signal and low overlap (IMHO)
changing the LCA moves both
here you'd think that moving from 114 to narrower would set the intake closed earlier and increase overlap (course you can set intake closed anywhere you want it but can't change overlap)
but here the shorter duration enabled booth intake closed to come out about the same even with the 114 LCA
