Overall Assessment

Customers have highlighted the product's quality and fit as key features. Reviewers noted that it was a close fit and stayed clear of plug wires, which enhanced its usability. They appreciated its practicality, with a minor modification needed in certain case to clear the steering column. Some customers had to modify the bolts for a perfect fit. Despite issues with fit in a few cases, the general consensus was that the product is well-made. Users recommend the product due to its superior adaptability compared to competitor products.

I have the engine on a stand making sure everything fits before sticking in the chassis. The header bolts are too long, need to shorten them or buy shorter. The collector bolts are too short, have to buy longer.

Installing sbc in 46 Studebaker. I'd used this same engine earlier but sold the car with prior headers. A set I had would not work with angle plug heads. Very pleased, fit and cleared everything with plenty of room. Speedway hits a home run again, and affordable too!
