Part # 9154622-SM Reviews I would purchase this product again Rated by Chuck on February 19, 2021 Summary: Best head for Imca Stock car Yes, I recommend this product. I would buy again Rated by butch on March 08, 2019 Summary: nicely done, ready to bolt on Yes, I recommend this product. good heads Rated by s10 on November 12, 2018 Summary: install was easy even in the 95 s10. However, the number 3 &4 sparkplug hole is centered between the head bolts which is slightly different from the previous heads we had. Holes were further aft. Only reason I bring this up is that we are using the Sanderson shorty headers which now get close to the #3 spark plug and prevents me from using a socket to tighten the spark plug. The boot on that plug is almost touching the header, but so far its okay. Yes, I recommend this product. Very nice heads. Cost is very reasonable.

I would buy this product again Rated by jim on January 10, 2017 Summary: The complete head does no longer come with guide plates Cons: Push Rod guide plates Pros: Rugged Construction Yes, I recommend this product.
