My home inspection of Speedmaster heads

Will these things take a 2.08 valve seat wise?



Yes but let me be the first to say it’s worth it but it’s not. A 2.05 pays the most dividends for time and money spent. The volume just isn’t there and gets VERY touchy. I had to flow ever single port multiple times to get my heads where they are. I started a need set of Edelbrock heads last year that I will move the rocker over .350 to get more area to see if that pays off
