ok, just put my head back on, its as below.
with the cam sheet i got with my cams, it says u have to set up the buckets with X amount of lift at TDC
in: .81" at TDC
ex: .125" at TDC
now, these are just base circle grinds, so thay havent welded them up and moved the lobe, when i first put the head back on back 6 months ago, i set he cams up to standard spots {slits on top of the cams vertical}.
now when i set them up to the specs they tell me, they slats are sittin at 10 and 2 {if u are standing at the front of the shitbox}, approx 45 degs.
that didnt work, valves hit, now i have tried to reset them up, but the exh is at like 12:15 and the intake is at 11:15, it will barely idle and when i try to drive it it has an odd noise {like a hollow noise} coming from the carbs, it'll rev, but makes no extra power as u rev it,
does this make sense to u, what could it be.
exacly wha does advancing or retarding the intake or exhaust cam actually do,
eg, retarding exhause make the power band higher ect ect
