Olive, You would want more than 11.5 comp to have and benifit with e85 and your cam.

I think your quote is quite good Gerg.

Wow

What does olive xm need btw xcsedan ? You almost stepped him up to pro stock with Kaase c400c's man 700-800+ lol ??? Lets not buck heads here Lets be realistic m8 iam not trying to compete with you. You need to put you feet back on the ground i think a bit. If ol mate wants this hp well he needs to say so and give a dollar value for the upgrade. Chi 2v heads to kaase is just rubbish talk. If he's considering some afd over chi big cfm heads he wants value not a top end race car engine with big cubes. Lets hear from him now. No one has big bucks atm XC. Shit has hit the fan in oz. Not sure what industry you work in.

Ok thanks for your reply and the exhaust info. What about the suggestion of having your chi 2vs heads ported ? Its alot cheaper. You can do those other checks requested before whilst at it ? Also the AFD 4v-s heads will make 600hp with the right cam and comp without crazy parts. You will need to do some slight cleaning up here and there like i said before but what heads a this price dont. They are great value i think. My AFD 4v-s heads were ported by Dave and i have a custom low to mid 260s @ 50 650lift on 108lsa dailed on 106icl solid roller on T&ds and 12.3 comp, renagate top loader and 4.11 9". Food for thought for you. Have a think about the porting idea anyway on the current chi 2v head.

Olive xm, Please feel free to ask any questions on the afd heads. Like i said earlier i am no expert but have used all Daves heads inc the afd 2v heads. Ask away. My opinion will vary to others but thats just what you get on the net. Thanks Carl

Thanks for your replyolive xm. If its at all possible, Could you ask your builder what icl the cam was dialed in at. What is your exhaust specs if you dont mind sharing. Diff ratio and stall size. Are you happy with the performance with the tfc or disapointed ?

Your absolutly right Gerg. But we are talking chi 2v heads here not cast iron units. Revised combustion chambers, moved plug location and runner over the ssr but we still have a 2v archititure. Would be great to hear from the owner of the car with the above question. Not tring to steal your lunch btw. Id be suprized if Sean has had these chi heads on his bench but ive been wrong before.

This engine is making 400rwhp with 2v heads which would make me happy with such a basic combo. Has this car actually been down the drag strip ?

No issue thanks for that Gerg thats us sorted. Ok we have a few un answered questions here the op can help us out with if he has not already removed these heads. Please let me tell you iam no expert but just passionate on the subject. Also please excuse if i missed it previously but what is the static comp, stall and rear gear are we running in this car. Dont forget the exhaust specs and icl dial in info from memory. Thanks

I dont think its off track Gerg, the OP was asking about afd heads on the page prevous. I just offered my two cents on that subject to help out. Now if the subject is falling over at 6k on std chi 2v heads and 393ci. What is the exhaust system specs and have the valve springs pressures been checked and what are the installed heights. Also what icl was this cam dialed in at. Cheers

you explained that very well. your right about the epoxi. Ive done this to my set of 4v-R heads too. I have no issues with this personally but many do.

The early afd heads were aussy cast. Ive used all the offshore 2v, 4vS and 4vR and still have my aussy cast 228 4v which are a nice peice. Alot of scattered info above guys some true some not. What did you want to know ? Also the rockers not lining up with the valve tip story, cut the guide plate and you can manipulate them till correct then spot weld, can be time consuming or just put some yt platunums on it or better T&Ds On the offshore heads you will need to like most clearance tbe push rod bosses to run 3/8 or 7/16 push rods. Cheers
