Reportedly, some will work and some are very abrasive. How do you tell ? NOS. Buick Stg. II aluminum heads with installed seats. Thanks, roverman.
Hi Art,
Why don't you speak to who installed the seats in the heads? Find out who manufactured the valves and speak to the respective manufacturers. Alternatively, speak to one of the reputable head porting shops, maybe take a head down and they will tell you what the seat is and if it works with that particular type of titanium valve?
Sorry can't be more of a help.
Regards
Jason
Jason, Head and seats are by Buick racing dept.(defunct). Buick power book,"alludes" to suitability.Thanks, roverman.
