Re: Porting Heads
Yes they will work, you have taken out the restriction under the valve basically.

Re: Porting Heads
It’ll be interesting to see the results
Re: Porting Heads
What compression ratio are you going for Pete?
Re: Porting Heads
I’d block the heat riser as well if I was me…

Re: Porting Heads
I have ordered a set of stock replacement Molnar rods and a set of Diamond lightweight racing pistons ,not sure what the final comp ratio will be as the block is being decked and honed as we speak but it should come out somewhere around 12.1 ....Block is being honed ,decked ,1/2 inch oil pick up fitted along with studs for the main caps .So pretty basic upgrades for a stock engine .....cam is a bit up in the air at the moment as i plan on getting one ground by Hughs

Re: Porting Heads
Are you going to run C12, or 99 octane with a splash of Race gas?

Re: Porting Heads
Having never personally blocked off a Heat riser, although I understand the benefits, how do they block them off ?
Do they fill with an epoxy or something else ?

Re: Porting Heads
Epoxy if you’re posh or melt an old piston down and pour that in if not….

Re: Porting Heads
Is that harder valve seat inserts installed there?
Is that best policy with no lead, even on US engines where they went lead free alot earlier than Europe?
I assumed the seats were hardened as standard or is that only 72 on?

Re: Porting Heads
Valve seat recession with unleaded fuel hasn't proved to be a problem with the limited mileage we do in these old cars Matt.

Re: Porting Heads
It's a filthy job to do but worth it in the end.
Are we there yet dad ..... 10 to the gallon but worth it.
