Hell Bent for Speed
Current heads are '68 302 'J' Code 4V heads heavily ported, but still have stock 1.78 / 1.45 valves. Spring pockets have already been machined & 7/16" screw-in studs w/ plates are installed. 1.6 roller rockers.
Assuming that I may have valves damaged & could potentially be yanking the heads off, I would want to upsize the valves since that was the only thing that I didn't do the fist time. Is it a simple upsize to a (standard ?) che\/y valve size - 1.94 / 1.60 over the stock 1.78 / 1.45 ?
Isn't this a typical Ford upgrade over the stock size?
I will farm out the head work to have the seats enlarged. But, what else is required on my end? Do I just buy stock che\/y valves - or it is a "special - enlarged" Ford valve that I'm looking for - for stem length, diameter, etc? Is it a 351 valve?
I want to be able to reuse my new springs, retainers, locks, etc that are already installed on my heads.
Thanks
