I bought a set of Patriot Freedoms 185s for my 351W roller . Haven't put them on yet.
Look like a decent quality head and I paid not too much more than Procomps. Got them from eBay from a guy who brings in bits and pieces. Not well known but they look pretty good.
You should have bought some AFR 185s that were eBay on couple of weeks ago. The seller was from this board. Cant recall his username at the moment, but he is from Darwin. Posts pretty regularly.
Went for $2k. Brand new.
For a stroker you might want to go something bigger.
Cheers,
Frank.
