Anyone use 1.6 & 1.7 rockers?
 

Anyone ever use a mixture of 1.6's and 1.7's?

Was it you that was talking about this recently?

I thought it was, or maybe it was someone over on the Corral.

Isn't it 1.7s on exhaust and 1.6s on the intake?

I'm curious about this as well.

sorry I was no help

Yes, it was, I was surprised earlier last week that no one had ever done this, it's no biggy, I was just asking it simply, looking for a broader responce.

When I was building my motor, and consulting with a friend he mentioned that same trick. 1.7's on the exhaust side, cause thats where the stock heads could use improvment. But I believe he said its only beneficial on stock heads, cause aftermarkets are well, built to perfection (if you will). He said people have been doing it for a long time, but that was the only time i have ever heard that. So who knows......

ive heard that you can gain some power with aftermarket heads with that trick too. i havent tried it myself but am looking into it, i have ported and polished edelbrock rpm heads on my 95gt. so i too am wondering if the gain will be worth it or not, if its only gonna give me 10 horse ill stick with what i have, ive read somthing about someone using this trick but dont remember where, hopefully they will come forward with some info for us.

Get a good cam and you won't need to mix and match. LOL.

I haven't, but on a set of stock heads the exhaust can definitely use the extra bump to help rid the cylinder of all spent gases.

However, as Kell said, if you get a good cam for your application (proper duration, lobe separation, lift) and especially if you match this with a nice set of aftermarket heads (a la TFS TW, AFR, etc) you won't need to do the "mix match suffle."
