    • Best bang for your buck. Very impressed!
As a guy that doesn’t have awhole lot of $$ to spend on the “high end” performance products, I decided to give these bad boys a whirl. Sure glad I did, these cylinder heads really woke up my old tired iron block, cannot find a full top end kit fit cheaper OR with this quality, they push out some great power and are made VERY well. I had a machine shop check them out and assembly them and they too were very impressed, Speedmaster is now and will be my go to for performance products. Don’t let the old reviews fool you, these are quality and Speedmaster deserves some recognition! ... show more
