rwysowski 1 I owe you an apology looking back at it I was rude, didn't realize you where replying to Toyo 321. I need bigger intake runners for the future. engine will see 2-3 seasons in the boat then it goes in a 55 Bel Air 2 door hard top, at that point I will need bigger ports no holds barred. again I'm sorry about the negativity.

Thank you, no worries it's all good. It's feast or or famine I had 2 people on eBay and 2 on offshoreonly all with questions and all I had was my phone. The app version doesn't show the last question when I was asking the question to Toyo. Sorry, I for the confusion. Best of luck with your build!

Thanks
Rick

Gents I personally saw these heads and they are beautiful. I did not need the heads but did purchase the other 525 components he had. He spent what ever time I wanted to inspect the items for sale. It was a clean easy purchase. Just putting my experience with rwysowski1 out there. Happy boating

Have those been drilled so stock 502 exhaust will bolt up?

Drilled? All BBC's, even gen 7 take same exhaust.

Mercury 525 heads have a proprietary exhaust bolt pattern. Easily overcome to standard GM bolt pattern
