Anyone have used the Pro Maxx CNC 227 Heads?
Hello, I came across a used set of Pro Maxx LS CNC 227 heads. I know this company bought Patriot Performance. Now I have been searching for information of people who have used them but can not find any info.
Is anyone here who have been used them and have experience with the Pro Maxx LS heads?
Thanks

I was curious how much the used set that you mentioned was going for. Reason I ask is because if they similar in price to say a good used set of ported 243's, then maybe you should consider that route. Unless it's a smoking deal I'd probably shy away from something that is so unknown. Might be a good reason for that

My logic was for $800 a set of heads with 2.02/1.57 SS valves 300cfm@.600 lift is not bad with 64cc. If buy them and them sale my 243s with .650 double valve springs for like $500. That mean that my out of pocket is only $300.
Now if send my 243s to TSP for 2.5 stage porting job is $1000 with no springs only head and valves.

Yes I know the history of the company. I stated in my original post. What I like to see are real testimonies of results from people who used this Pro Maxx heads. I never know if they modified the CNC program or have a mayor changes from Patriot because I heard from people that used Patriot last productions heads and they said the quality was to bad..

I’ve seen them around on SBCs, seem like a decent value. If it was me, I would swap out the springs and hardware they come with. I honestly haven’t heard of failures, but it seems like cheap insurance to get quality hardware to keep the valves from kissing your pistons.
