OK, getting ready for the weekend here as that is probably the only time I can take a shot at improving these a tad more.
Q1 - Re: the exhaust port roof guide hump, am I getting a YEY or NAY kind of an answer here gents? LOL
I am asking literally some suggestions as to whether I should even attempt to touch this or not? Seems like just a chunk of metal that only supports the guide while at the same time restricting air from passing through the port.
Q2 - Re: the intake port roof, I am going to remove some metal there to give the turn a longer and rounder turn towards the valve...I think there is space there, my thickness checker will come in handy here, is there anything here to really worry about? seems like a straight path the only obstacle being the head-bolt passage...
The plan is to do one cylinder, do a final flow-test and either replicate, or find a hole somewhere to hide in case I mess things up!
Thanks everyone...
The trouble with a lot of these heads on the exhaust side is the shortside has what I call a “Herman monster forehead” that over hangs into the bowl. It’s been awhile since I’ve touched a W2 but on Speedmaster, Edelbrock, etc, this area needs pushed back, widened, and then shaped. This save the exhaust air from going around Herman’s forehead and out the port.
