Wonder why they stopped making em? Covid? Ha!@sigsterrr did a pretty nice build with the SVE heads. I felt like it was more recent, but just looked back and it was about a year ago now! I guess he got them before they stopped selling.
Im looking at Blueprint heads now $1010 for a set. #9001 good reviews on Summit . They have a better base,. with even more Chieesium.
There is zero chance i'd be buying a budget off brand head and not taking it to the machine shop to be valve jobbed.
They could very well be good (although promaxx I believe is formerly patriot heads), but can you really risk running them without having them checked first?
A hci swap is a lot of work and money, I just can't see trying to save $200-$250 as an experiment with all that work.
In general they are correct that most inline heads with 2.02 intake valves won't clear vs. TW heads with 2.02 valves that generally will clear.However, depends on the cam duration, head gasket thickness, block deck height, and about 10 other variables. You can also notch the stock pistons which is why you check PTV clearance.Those heads have a 2.02 intake valve. I have been told by afr tech support that their 2.02 intake heads will not work with the stock pistons.
This is what I am thinking. I want to buy a set of either cheapo heads that have the same configuration as stock, and use rockers, valve covers . Get new pushrods and AFR bolts. No cam because I dont want to dig that deep. I have four inch Power pipe 80 mm Accufab throttlebody, Pro M meter, 19 lbs inj. Bassant X , Shorty headers. So Im set up for heads. My skills are average , so I really dont want to take the motor down to the bones. I dont drive that fast. looking for reliability. My E-7 heads are suffocating me causing jumpiness . Also I am very aware of the negatives , but I am the sole bread winner in my house.. Will it go much better / faster.
For me it's simple when it comes to things that are a lot of work, I'm all in or all out.This is what I am thinking.
