[mrmut]

Convert 1300 to 1600 dual  head.
Head of 1300 F engine to rewrite the hole cylinder 89.-- to 93,-- whether the head wall will be thin.
This conversion reduces the 7,5:1 to 8,8:1 CR

Which in context ,I do not understand

This conversion reduces the 7,5:1 to 8,8:1 CR  from 7,5 to 8,8 is an increase/more/higher CR

Do you want to convert a 1300 to a 1600 dual port head?

Yes. 1300 dual port head to a 1600 cc cylinders

Then you need to bore the heads. Could be easier to buy 1600 heads

I have 1300, 1500, 1600 heads. I want to try 1300 or 1500 in 1600 , аnd 1600 to open the cylinder 90.5.(1776cc)
I have three engines , and I have two 1303s.

1-1303s to be a 1600turbo
2-1303s to be a 1776 with 2x36 drla

Hi there,

I like your plan, machining heads is the best thing to do in your spare time 

Just thought "F" engines always have singleport heads. Dual ports should be from a "AB" engine.

I got only one doubt about it:

Dual port heads for 77mm bore in good shape are getting very, very rare and they are (nearly) the only way to get 12oocc engines converted to dual port engines. In my opinion it would make more sence to build a quick 12oocc from those heads. You can (if you are willing to spend hours & hours) get 100 hp+ out of 77x64.

keep workin`...

just my 2 cent
