I was going to go with Advanced Induction or Lloyd Elliot for my head work but im waiting for a response to see if they even do L98 Heads please let me know of any excellent people that have worked on L98 heads and the results thanks for your help!!!

 

I am not sure if Lloyd does iron L98s but he does do aluminum L98s. I got a quote from him before when I considered doing those heads and it was the same price for his LT1 heads except you will not get the advertised CC runner size and flow since L98s cant be opened up as much as good Lt1 castings.

you can get 195-205cc with an LT1 and approach 280-290 cfm maybe more. L98's I got quoted to 260 cfm for his LE2 type port job with valves and fully ported.

Many years ago here there was a member who hand worked iron L98s and got 270 cfm out of them and well over 200 onthe exhaust. Very nice work but very time consuming.
