which head will get you less detonation for a high compression moter?

 

sorry bout f@#king the title up thats what i get for posting when i was tired

 

There are many other key components inside an engine that may determine its resistence to detonation or pre-ignition besides the head.

true but the head is one of them, just wondering if the pentroof combustion chamber in the gsr helps prevent detonation in a high comp. build

 

anyone?

the gsr should be better , less edges, but it has higher compression which could cause detonation so its a give take thing.

 

can some one post pics of the combustion of both of them

 

type r head w/ rev valves, notice how there is a full circle around the head, that edge is really sharp and is there is a full circle instead on a gsr head that area above and below the valve is totally flush with the head instead of being inset like the type r shown so in theory the less edge there is the less chance of a hotspot occuring which in some cases causes detonation. if you were to totally redo a gsr head imho the gsr head would be my choice. better angle of entry for air and just a better design to work with compared to a type r, a lot of people on here might not think so but remember thats just my opinon don't flame, its just honest forward FIRSTHAND advice.

 

cool good to hear i just bought a gsr head tonight

 

what kind of question is this?

Not really. You man noticed that alot guys used either or.

Sorta like what basketball sneakers is better. There's alot of factors that one type will do the same.

 

its a give or take thing, gsr has higher comp which could cause detonation but it has less hotspot percentage which could lower the chace of detonation. motors suck we all shoud pedal around and get in shape instead
damn atkins freaks gettin too me

 

so compression being the same, gsr head will detonate less

 

I have had better luck with GSR heads.

 

cool thanx
