sbc chevy aluminum heads top end combo 350 383 406 quality parts & assembly ARP 

Mrperformanceparts is proud of the items we sell. We are careful to research our products and select parts that work. (not just parts to make an attractive price) we spend anywhere from 2 to 9 hours on our heads making sure the parts you get are parts that will work. We offer only jet flo valves no substitions for any reason. 300 or 800 hp NOS turbo whatever that is the valves you will get. They are everything others “claim” to have in their heads but are actually not even close. No games no price point assemblies, no BULL. We offer only heads that are inspected, machined, valve seats are cut, valves are lapped, springs are shimmed. All the things you should do with any head no matter the brand name stamped on them. I can take a set of 2000.00 castings and make them junk in 5 minutes or less. Cheap parts thrown together and the price sure looks pretty! We feel if you spend a little time, put in some quality parts you can still make a great head at an affordable price. And have it last! We have all seen the horror stories on many message boards, one got them and love them next guy had major issues. Well… only difference is where they came from. We buy in large volumes and get the best prices and make pennies on every set, If others are doing the same work and using the best quality parts, then they are going in the hole on every set! And I bet that’s not happening!!!!!

We are a small local speed shop and will always be that. A total staff of four people. Our lead machinist with over 35 years of race motor experience, and was a tool maker before that. And or I personally assemble every set of heads that come out of our shop. We stick with the motto if you want it done right….. J Two of our staff even work in the tower at our local race track every Saturday night! We honestly live and breathe performance. We are family run and family worked shop and will always be. From heads to ignition systems and complete motors we do what we do for fun. I don’t want anyone to have anything I have never used or wouldn’t use on my own vehicles. Yeah there is a lot of cheaper parts out there…..just not the same parts!! Just look at the pictures…check around….What we do DOES MAKE A DIFFERENCE!!!!!!!!!!!!!!!

I see some of come and stepped up some. We feel great that we have helped to cause this change. And hope many more will follow the trend! While there will always be those that sell 100% price point And cause issues to those that don’t consider themselves to be “billy bo bobs midnight auto parts and beanie baby emporium” check out the videos below!! affordable heads built right can run against you anywhere. We do our very best to make sure that our chain has no weak links. Vto seals, pep springs, studs, guide plates, shims, retainers and locks, true jet flo stainless 1pc (honestly not claimed) undercut, polished hardened tip valves (just look at the pics and you decide what you like).

We can set springs to your cams specs and we have spring options that are countless (prices vary) titanium retainers, we do have some common builds as many cam companies have multiple grinds that use identical or nearly identical spring rates now days.

(far more then you would think)

several spring options at the exact same prices and no additional charges other then parts if you have a cam outside the normal builds (why would you pay to have heads built twice?) Again not in the business of mass volumes we treat our online customers like you live right down the road! Ask questions before you spend your $ its cheaper to do that the first time rather then when you are buying a second set J were not perfect, but we try harder to be. In then end its about FUN not about mass volumes or selling 5000 different items and a bazillion feedback. No one including are many racers, rodders, mudders and just those that have fun both local and over the world. Will ever see anyone at our retail location or warehouse hugging the counter. Our main page of our own website shows many customer cars, we do the grand prize donation for our local car show, and donate to local area racing museum. I am a third generation racer, raised in the race shop and tore down my first motor at age 6. we don’t hunt or fish we just play with hotrods. Many pics you see are cars that were built in our shop. With the same love you would give to your first born!!! (I know I hear about it a lot J)
