Brand New - Never Ran - LA Small Block Speedmaster Aluminum Heads
Brand New - Never Ran
LA Small Block Speedmaster Aluminum Heads, springs are for flat tappet 65cc
Both heads passed my inspection, for threads, and gasoline leak check, no valve leaked fuel.
Here is what I know; I like the castings they are quality, I purchased these primarily to save weight but this detoured me from my original goal of a compression ratio that I was locked into with my 318 decked .03 block and flat top sealed power hyper pistons. So I am back to original plan of iron magnum heads. I installed on engine only. For the purchaser, I have details of spring dimensions, and head bolts needed (the company's site is wrong). Thank you from mopar daily driver
