The heads fit perfectly and were easily applied to the 46 Merc. Block. We started the engin in a stand and they sealed perfectly. I look forward to many years of service when I get the motor installed in my 49 pickup . Thank you every one at Speedway!!!!

I have wanted a set of BLOCK SCRIPT Edelbrock heads for years now, and finally got a pair from Speedway. They were easy to install (would be worried if they weren't), and sealed with the block the first time. Obviously at .410 chamber height, valve clearance for my street-driven rod was no problem. Eventually, I plan to on using these heads on a replica of a specific early lake racer, and look forward to many years of use. Unfortunately, I don't know what they look like compared to the original BLOCK SCRIPT head, and hope they appear a dead-on copy when installed.
