Auto Parts: vortec head swap, chevy silverado, pep boys

Question
I'm debating on swapping out the heads in my 1990 chevy silverado k1500(5.7L tbi) for a set of vortec heads. I was hoping you could offer some advice as far as specs I should be looking for to make a straight across swap... I realize I will have to swap out the intake and exhaust manifold but but as far as the cam/timing/etc, will they pretty much remain the same...

cheers,
s

Answer
Hi Seth,

I'm ONLY seeing one style of heads for that engine displaying cast numbers: 10065204, 10159550 or 14102193. Whether they be Vortec or not, I'd have no way to tell. The notes state that the proper head for that engine should have the four center intake manifold bolts screwed into the head at an 80 degree angle.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
