dudes!!
i have a minor querie and small problem. I have just purchased two head for the 18rg. One is a ported and polished 88230 head with 45 and 37mm aftermarket valves. The other is a 88250 head which is bog stock (45/37mm valves).
Now the engine i have in my old celica has an 88253 (!?!?) head. So WTF head is this??? So far i have only found (and inferred) this information:
11111-88230 = 18R-G
11111-88250 = 18R-GU
11111-88270 = 18R-GEU
do i have like an 18R-GRU head or something crazy like that!?!
Also would like to know what you guys would recommend i use as the head for my engine im rebuilding? I have read that the later model 18R-GU had a better head flow than the 18R-G, but would the porting and polishing on the 88230 head i have overcome these flaws and outperform a stock 88253 or 88250 head?
Im just lost for thoughts here guys!!!
Will post pics in a sec
