I have used a few different Pro Maxx cylinder head castings and those all seem to be really good. I can not vouch for any of their other parts, though.

I have also used a couple pair of their cast iron "Bow Tie G.M. Vortec" coppies with very good luck.

I have a set of their SBC heads on my car. Bought them back when they were switching from Patriot to Promaxx. I've got 20K miles on them and haven't had any problems with the hardware they came with.

Don't plan on using much power adder on a Windsor, They only reccondmend a max of 80 pounds of torque on the 351w. Nice casting, Very hard aluminum, good for bolts probably not so good for not cracking??https://www.facebook.com/#
