I noticed the thing with the exhaust ports too. A 5.3 head gets better flow with a smaller valve than a magnum head. Heck, the LS3 heads have tiny 1.59 exhaust valves that can flow in the 190's @ .500 with that port. Thats still a smaller valve than the Magnum.
Old tech head w/a MP 1.60 vs new tech LS 1.59, not a whole lot to gloat about there! Why not bring up a poly head for comparison?!?! LMAO. I’m not beating on you bro. This just reminds me of a guy that I used to work with. Chevy is the GOD for him.
He walks in on a conversation with me and another and asks why the MoPar is my choice. He instantly jumps how inferior MoPar is by jumping to the LS when I’m talking about/working with a LA or Poly head. And! The years difference between them is not of any consequence. The fact that technology rolls on people get smarter and invent better stuff doesn’t count.
We have been shown the better the cylinder head up top the better the power for decades while most common complaint here is how **** sucks for us and the SBM TF head is said to be to much on a street and a low compression engine. (Under 10-1)
That and (insert a cam spec) is to large and to much lift for the street, you will be doing maintaining duities 2 times a month of your valve train (more bullshit) changing spark plugs twice a month, (and more bullshit) and etc…..
There is a sea of people crying the blues but yet ignore what has been shown over and over and over again.
I’ve been saying this for so long, put the best head you can afford up top and lift your valves as much as the head/springs can handle and power will be granted. Works each and every time.
(Now enter the clowns telling me different even though Detroit has been doing this for a good while now, member IQ52 demonstrates this in his threads, as well as a few other members….)
But yet they come back with an excuse and some scientific babble as why it’s a bad move or won’t work. There bullshit is so good it almost can convince me if I haven’t already done it half a dozen times.
