tahoe misfires corrected

i had a lot of problems misfires on my 99 tahoe, especially uphill under load, replaced every thing known to cause it, until we pulled the heads, the valves were actully hanging up , some even hit the pistons out of there groove. gm has a service bulletin out on this, installed reman heads ,problem solved , finally!!! i loaded up 4 atvs on the trailer, headed out and it will actually hold 75mph up and down hills no problem. lot more power than before and no MISFIREs!!!!!!
