Thread: Engine Quest Heads?

Tweet

Has anyone had any experience with the 235cc heads they offer? I'm building a 406sbc with a little over 700 lift and I'm wanting alittle breath up to 7500rpm.

i used there replacement heads. i think there heads are pro top line heads

Thank's for the reply. Seem's nobody has had much experience with these head's, I just might give them a try.

well you could ask who makes them. there was a time i did get someone say they were protopline heads.now a comp cam RHS?? i did read some were? i would look at the PPB /dart heads and pass on there heads less they say they will take them back if there so so and tells you who makes them.they did give me some crap on some of there OEM replacement casting telling me i was the only guy that was not happy with them . i had them go thru many new heads to find two head casting i could use and at best they were ok alot of shift in the casting the ex seats were hanging off side in the port i did not think they were a hot deal at the time i look at them???

Go with AFR

Yea at 100 dollars a piece bare for 235cc it does make one wonder, Thank's for the feedback. I currently have a set of World Product Sportsman II 200cc and they do good but are not going to be enough for the new build and there's alot out there with big talk about how good their's are and money is alway's a factor.

well buy them look them over or have your machine shop do that. if ok use them as long as you can send them back if out of wack .i think there pro top line heads and for a iron head they did flow good number.i know they were a hell of alot more then that when i look in to them but i think comp cams now owns pro top line now RHS .so engine quest is selling them off???
