i read through the archives and there is no clear answer to this. I have a sset of 87-88 l98 heads that were given to me. Are they worth a build up? I mean dollar for power can they be made to perform? I local shop says $150.00 for 3angle valve job and $100.00 redecking. Now figure 200-300 more for R/R'S and springs. What do you folks think? thnks THE SHAGGY IROC

so much to do , so little money

iron heads will make more horsepower than aluminum heads of the same size. port the crap out of em, give em valve jobs, 1.6rr, and mill them a little and you will have some good heads.

I hogged the snot out of my L98 heads and it made a big difference.I get about 600 or 700 more RPMs out of the top end before it pukes out.I'm sure its not the same as buying after market heads,but all I had to do was buy the porting kit ($36.00)and get a valve job($105.00).
