Cam's done, now im thinking of getting some 1.6 roller tip rockers. All I want to know is if anybody out there with a 305 has done this with enough clearance in the heads.

Thanks

I have some on an 86 305 with no problems.

 

Shweet, steal?

Notice any difference? Word is there isn't much.

If you already have an aftermarket cam you will see proably nothing for gains on a stock headed motor. Stock heads are way done flowing by .4-.45" lift so the extra from 1.6s won't do much for you, and the roller tips friction losses aren't worth the $$$ unless you have money to blow and everything else is done.

 

Well spose I better move on to headers then..

But my lift on the cam is in the .44 range, not even at .45 yet...

I had to be carefull with the cam, and im glad i was after what i found in my engine when i tore it apart...

i just put in a LT4 hot cam with the 1.6rr in my 305 TPI, no problem with the it hitting the valve covers.
