1.88 intake valves

rigger3006 said

i had my 302s rebuilt and ported by a reputable mopar shop and asked for the 1.88s ,the builder said it was a waste of money in his opinion, but would do it if i wanted. instead i got the exhaust opened up to 1.60 per his thoughts, with bowl porting being done.eventually i went to a 360 and wished i had gone 1.88s also

You bet you wish, the exhaust port of a 318 head is miles ahead of the intake port.
They actually flow better ported at 1.50 than a 1.60 360 head equally ported
Equally, meaning I can bowl and sort turn a 318 port in about 15 min...it takes 30 or so..to do a 360 exhaust port-more material removal involved. .. and even then the turn isnt as good.
Stock valves and ported is the best bang for the buck. You can get 200/175 cfm int/exh with ease.
Also... few people realize the 1.78 318 I take valve is more of a nail head whereas the 360 1.88 is a big tulip that eats up more bowl volume.... 1.94 cut down or forget it imo....otherwise just use a 1.94 and go bizerk
