Hey, no different than any of us who've struggled over the years to figure stuff out.......... I still struggle..........

But my struggle is on a computer... I dont even
have to get out a wrench.... plug in

40 plus years of changing carb jets for me and I will continue doing so. Way to many carbs sitting here and very happy with their preformance.

By the way what the heck does this have to do with ProMaxx heads. Wholly post robber Batman. Lol

At least it hasn't degenerated into the usual quagmire of name calling.

Sorry.. no more comments out of me

That's a Small Block Chevy Head he's cutting up. NOT a Mopar head.

Oh I know and will be sonic checkng mine befor I start porting. These heads are my friends and are going on a steer car that may hit the track once in awhile. I really try to stay off the bottom as much as possible but it's nice to know meat is there if needed. Edelbrocks are a little lean in that area

Hey can we get an update on these heads?

I edited some of my detracting posts, Im a real dick some days.

But since you have hands on these heads...... whats the report card look like?

Like I said above this was a freebe job for a friend. It is still mounted to my flowbench as I ended up in the hospital with a few health issues and I'm very limited in what I can do until hopefully getting straightened up. If my health returns I will have a set of my own and will dig deeper into them. Th four valves that I removed so far feel great as far as valv guide clearance. I told my friend that if he wants to come over some evening and tear them completely apart I will assist him so he can as a 22 year old learn the process. I truly like what I see so far and will update when I have more info. This head will go 300 plus CFM with little work

Hope you heal up soon.

Thank you very much

Mr. Pittsburghracer:

I really appreciate your contributions to our hobby. Get well soon and get back to the wrenching!!!

John, I hope you heal quickly. I to enjoy your tech posts and contributions to this forum. I will be praying for your speedy recovery. Jim

I just hope you get better to get better, screw the web and car stuff, getting older and dealing with health issues suck!

Thanks guys and fingers crossed all goes well soon. Its crazy how good you can feel at 59 years old and how quickly a bad spell can set you back at 60. Last year i started walking and called it my RiverWalk program. I cut unhealthy carbs and worked up to walking 4 miles a day 5-6 times a week. I lost 55 pounds and although I didn't hit my target I FELT GREAT. Then Winter set in and stupidly I stopped instead of going to the gym. On on the downhill slide we went with 4-5 health issues so far this year. I started walking again this week for the first time since April so now its up to me and the Doctors.

During the time this post started going south 7-23-16 to 7-24-16 I was sicker than a dog and ended up in the emergency room. I apologise if I offended anyone but posting from my cell phone only I was trying to keep this post on point for myself as much as others so hopefully some good info could be shared. Trust me I tried to research them before my Friend bought them but there is almost NOTHING floating around. I'm super glad he bought a set of heads that put Edelbrocks to shame and I for one will never buy another set of Edelbrock RPM's till the issues are addressed. Victors???? yes I hope to have a set SOON.

wish you all the best healing up

Dateline, Pittsburg 8/24/16: Any updates????? Hope you are well, sir.

Do they have a magnum version??

No updates, I'm finally back in the shop some and he was sick. Its up to him now to take them apart with my tools if he wants to and check the remaining valve guides. The 4 I took apart to flow the head were great. As I said earlier everything I did on these was free and he won't be charged. We both wanted to see what the flow numbers were so I threw the FREE part out there. Now its up to him to take the rest apart to check the rest if he chooses to do so. I'll help but I have to much of my own work to do. I'm still slowly getting my stamina back but by time the yard work is done and my 3 mile walk I'm to tired to hit the shop for very long. Thinking I will buy my set bare, have them opened up for a 2.08 valve, push the pushrod over, port them, and see if I can improve much on the hair over 315 cfm I've gotten out of a stock location pushrod on my Edelbrock heads. If I can't find 325 PLUS its not worth the added costs.
