new rockers
new rockers Im thinking about getting some new rockers, either yella terra 1.7s or harland sharp 1.7s. how much of a power gain would this be, and would it need to be retuned after they are put in.
No tuning would be needed. You really don't need new rockers unless you are worried about the needle bearings spilling. You would get very little if any power gain from aftermarket rockers.
I think they are. You will have less guide wear and you can obtain a very narrow wipe patter with the YT's. As for final hp gain, maybe 5 hp but don't buy them for that, buy them because of the better valve train geometry that can be obtained if you set them up correctly.
