Alright so im finally getting to the motor work on my 86lx. the thing is the motor is older than the car. not sure on casting numbers but i do knows its a pedestal mount hydraulic flat tappet motor. So im ready to pick up some gt40p heads with new 1.90/1.60 valves and 5 angles port job for $300. i know ill need a different size push rod. But just wondering what else ill need. i am planning on changing the cam while im at it but not sure to convert to a roller. which im not even sure what is required for the conversion. last is what style rockers i should go with. and if i go to a bigger cam should i stay with a ratio of 1.6 or can i get 1.7 rockers. thanx for any input.
