S/R Torker Bare Head
Rated
by sanshonede on October 11, 2016
Summary:
I think these heads are a lot better than wasting a lot of time and money on built up junk heads. I am working on an economical stock engine that will not carry a lot of old baggage. For competition and high power there are better heads but these will be adequate for my build.(moderate-hi performance stock street)
Cons:
Open Chamber
Pros:
Center And Edge Valve Cov
Clean Well Machined
Excellent Workmanship
Good Valve Seal Options
More To Work With
Thick Castings
Yes, I recommend this product.
