Hey I was wondering if anyone knew much about swapping or upgrading the heads on a 4.3 v6 silverado. Whats the price and gains of doing it and I would like to know if it is worth it.
X2 he said it better than me! the 4.3L vortec in your 2000 already has pretty good flowing heads as i mentioned. So doing that will help since for the cost any more spent on a 195HP V-6 is kinda throwing money away except for improving up the factory goodies with a cam and things like that. if you really want more power a blower would do you some good. However the down side is they cost $3K plus and if you really want more motor you can simply sell yours and buy one with a 5.3L in it and you get 295HP right out of the box. However i know you may be attached to your truck so power adders are always a great thing.On a street head, gasket match the intake, exhaust and clean up the valve pockets. As long as you have the heads and manifold off do a camshaft change.
